Скрипты GOsA предназначены для удобного администрирования каталога на основе Open LDAP. Данный проект позволяет наглядно визуализировать объекты, находящиеся в LDAP-каталоге. Причем отображение объектов происходит только в том случае, если в их описании присутствует какой либо из специальных классов, зарегистрированных в схеме gosa. Такой подход не позволяет использовать какие либо другие проекты, работающие с LDAP-каталогом, без существенной их модификации. Соответственно, если планируется использовать базу LDAP только для администрирования пользовательских аккаунтов в локальной сети и для интергации с Samba, то лучшей админки просто не найти. Если же в дальнейшем планируется использовать какие либо еще приложения, например, Open Xchange, то использование Gosa – непреемлимо.

Установка Apache 2

# apt-get install apache2 apache2-common apache2-httpd-prefork apache2-mod_php5 gosa-apache2

в файле /etc/httpd2/conf/sites-available/default.conf в строчке servername прописываем доменное имя разрешенное в DNS. в данном случаи gosa.office.etersoft.ru

В этом же файле делаем после модуля

<IfModule alias_module> # #Alias # </IfModule>

пишем Include conf/addon.d/conf.gosa

В самом же файле (/etc/httpd2/conf/addon.d/gosa.conf) раскаменчиваем нужное...

Alias /gosa /var/www/html/addon-modules/gosa/ <Directory "/var/www/html/addon-modules/gosa/"> Options None AllowOverride None Order allow,deny Allow from all </Directory>

стартуем сервис

# service httpd2 start

Устанавливаем PHP5

# apt-get install libapache2-mod-php5 php5 php5-cli php5-common php5-dev php5-gd php5-imagick php5-imap php5-ldap php5-memcache php5-mhash php5-mysql php5-pgsql php5-recode php5-snmp php5-sqlite

Вот эти установлены были в итоге

php5-5.2.3 php5-imap php5-mcrypt gosa-php5 apache2-mod_php5 php5-dom php5-ldap php5-snmp php5-cups php5-libs php5-memcache php5-suhosin php5-simplexml php5-mhash php5-mbstring php5-gd2

некоторые модули могут не устанавливаться, а может они и не нужны ))

В php.ini меняем значение на приведенные ниже:

register_globals = off session.gc_maxlifetime >= 86400 session.auto_start = off memory_limit >= 32 implicit_flush = off max_execution_time >= 30 expose_php = off magic_quotes_gpc = on zend.ze1_compatibility_mode = off

Тестим на работоспособность, запускаем в браузере страничку gosa.office.etersoft.ru и gosa.office.etersoft.ru/gosa/

При запуске веб-интерфейса могут возникнуть проблемы с phpinfo()

решается она закоменчивание в php.ini строчки disabled, или тому подобное, в которой собственно и есть эта функция. Также стоит сменить значение в safe_mode = Off и safe_mode_gid = Off

Затем в php.ini правим строчку allow_call_time_pass_reference =Off на On

И наконец ставим пакет perl-Crypt-Smb Hash

#apt-get install perl-Crypt-SmbHash

Установка LDAP

# apt-get install slapd

Также следует установить

openldap-clients libldap-devel libldap openldap openldap-servers

правим /etc/openldap/slapd.conf (со вкусом и знанием дела)

вот таким он стал в итоге

#slapd.conf include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/corba.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/java.schema include /etc/openldap/schema/openldap.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/misc.schema include /etc/openldap/schema/trust.schema include /etc/openldap/schema/gosa/samba.schema include /etc/openldap/schema/gosa/gosystem.schema include /etc/openldap/schema/gosa/goserver.schema include /etc/openldap/schema/gosa/gofon.schema include /etc/openldap/schema/gosa/goto.schema include /etc/openldap/schema/gosa/goto-mime.schema include /etc/openldap/schema/gosa/gofax.schema include /etc/openldap/schema/gosa/openssh-lpk_openldap.schema include /etc/openldap/schema/gosa/gosa.schema include /etc/openldap/schema/gosa/fai.schema include /etc/openldap/schema/gosa/dnszone.schema include /etc/openldap/schema/gosa/rfc2739.schema include /etc/openldap/schema/gosa/kolab2.schema include /etc/openldap/schema/gosa/phpgwaccount.schema include /etc/openldap/schema/gosa/pureftpd.schema include /etc/openldap/schema/gosa/phpscheduleit.schema include /etc/openldap/schema/gosa/pptp.schema include /etc/openldap/schema/gosa/dhcp.schema #include /etc/openldap/slapd-access.conf access to dn.exact="" by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write by * read access to dn.base="cn=Subschema" by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by dn="cn=proxy,dc=office,dc=etersoft,dc=ru" write by * read access to dn.subtree="dc=office,dc=etersoft,dc=ru" by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write by * read allow bind_v2 concurrency 20 #gentlehup on sizelimit -1 loglevel 1024 password-hash {CRYPT} pidfile /var/run/slapd.pid argsfile /var/run/slapd.args replica-pidfile /var/run/slurpd.pid replica-argsfile /var/run/slurpd.args rootDSE /etc/openldap/rootdse.ldif #access to dn.exact="" # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by * read #access to dn.base="cn=Subschema" # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by dn="cn=ldapadmin,dc=xen,dc=local" write #access to dn.subtree="dc=office,dc=etersoft,dc=ru" # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by * read #access to attrs=userPassword # by self write # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by anonymous auth # by * none #access to attrs=cn,uid # by self write # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by anonymous auth # by * read #access to * # by self write # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by * read modulepath /usr/lib/openldap moduleload back_hdb.la moduleload back_monitor.la moduleload back_null.la #sasl-host localhost #TLSRandFile /dev/random #TLSCipherSuite HIGH:+SSLv2 #TLSCertificateFile /etc/openldap/ldap.pem #TLSCertificateKeyFile /etc/openldap/ldap.pem #TLSCACertificatePath /etc/openldap/ #TLSCACertificateFile /etc/openldap/ldap.pem #TLSVerifyClient 0 include /etc/openldap/slapd-hdb-db01.conf

файл /etc/openldap/slapd-hdb-db01.conf

# slapd-hdb-db01.conf database hdb suffix "dc=office,dc=etersoft,dc=ru" rootdn cn=administrator,dc=office,dc=etersoft,dc=ru rootpw secret #readonly off directory /var/lib/ldap/bases/office.etersoft.ru #index objectClass eq #index uid,uidNumber,gidNumber eq #index cn,ou,mail,surname,givenname eq,sub,subany #index gosaSubtreeACL,gosaObject,gosaUser eq index objectClass eq,pres index ou,cn,mail,surname,givenname eq,pres,sub index uidNumber,gidNumber,loginShell eq,pres index uid,memberUid eq,pres,sub access to attrs=userPassword by self write by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write by dn="cn=proxy,dc=office,dc=etersoft,dc=ru" read by anonymous auth by * none #access to attrs=cn,uid # by self write # by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write # by anonymous auth # by * read access to * by self write by dn="cn=administrator,dc=office,dc=etersoft,dc=ru" write by * read

Дальше запускаем service slapd start

Создаем два файла в корне

admin.ldif

dn: cn=administrator,ou=people,dc=office,dc=etersoft,dc=ru objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: gosaAccount uid: administrator cn: administrator givenName: administrator sn: GOsa main administrator userPassword:: dGVzdGVy #Password is secret (пароль захеширован, пароль secret)

и administrator.ldif

dn: cn=administrators,ou=groups,dc=office,dc=etersoft,dc=ru objectClass: gosaObject objectClass: posixGroup gosaSubtreeACL: :all cn: administrators gidNumber: 999 memberUid: administrator

дальше выполняем команды

#ldapdelete -x -D "cn=administrator,dc=office,dc=etersoft,dc=ru" -w secret "cn=administrators,ou=groups,dc=example,dc=net" #ldapadd -x -D "cn=administrator,dc=office,dc=etersoft,dc=ru" -w secret -f admin.ldif #ldapadd -x -D "cn=administrator,dc=office,dc=etersoft,dc=ru" -w secret -f administrator.ldif

Первая команда необходимо для того чтобы удалить уже созданную группу, она появилась при установке пакета самбы.

Замечания:

Выше приведенные два файла ldif работают у меня через раз. Поэтому я пришел к выводу, что лучше использовать свои:

[shan@testing openldap]$ cat adm1.ldif dn: cn=administrator,ou=people,dc=office,dc=etersoft,dc=ru cn: administrator objectClass: top objectClass: organizationalPerson #objectClass: inetOrgPerson objectClass: gosaAccount uid: administrator #givenName: administrator sn: GOsa main administrator userPassword: {CRYPT}jncgr52bkvktw

[shan@testing openldap]$ cat adm2.ldif dn: cn=administrators,ou=groups,dc=office,dc=etersoft,dc=ru cn: administrators objectClass: gosaObject objectClass: posixGroup gosaSubtreeACL: :all gidNumber: 999 memberUid: administrator

[shan@testing openldap]$ cat adm3.ldif dn: dc=office,dc=etersoft,dc=ru dc: office objectclass: dcObject objectclass: organization #dc: office.etersoft.ru o: test

Теперь в поисковике (browser) набираем gosa.office.etersoft.ru/gosa

и следуем по шагам, не пугаемся немецкого, на второй страничке язык можно сменить на русский.

но для начало в консоле вбиваем предложенную команду echo «здесь должен быть какой-то текст»

на одной из страниц будет предложено ввести имя админа, вводим cn=administrator,dc=office,dc=etersoft,dc=ru и пароль.

На странице проверок схем проверка может не пройти, поэтому выбираем не проверять схемы.

дальше настраиваем как нравиться и по вкусу.

и один из последних шагов – создать учетную запись Сис.Админа ГОсы, создаем и продолжаем дальше идти по пунктам.

в конце будет создан файл gosa.conf, его нужно сохранить в /etc/gosa/

и после прописать пару команд для его защиты

chown root.www-data /etc/gosa/gosa.conf chmod 640 /etc/gosa/gosa.conf

жмем дальше и попадаем в меня приветствия, где вводит логин и пароль сис.админа госы и попадаем в оболочку.

Установка nss_ldap и pam_ldap

Во время следующих настроек советую держать 2–3 консоли под логином рут.

# apt-get install pam_ldap nss_ldap

Вместе с nss_ldap поставиться nscd. Не забываем запустить это сервис.

Далее редактируем в /etc/nss_ldap.conf

вот так он выглядит у меня, это рабочий вариант с анонимной аутентефикацией. Это вариант плох тем, что в этом случаи можно устроить бруд-форс атаку (это плохо, но как вариант :) )

Затем делаем ссылку на этот файл, т.к. он содержит уже описание для pam_ldap

ln -s ./nss_ldap.conf ./pam_ldap.conf

Настройка PAM для работы с pam_ldap

Настройка pam для pam_ldap очень проста – Вам надо лишь добавить строки, начинающиеся с '>' в файл /etc/pam.d/system-auth

#%PAM-1.0 > auth sufficient /lib/security/pam_ldap.so auth required pam_tcb.so shadow fork prefix=$2a$ count=8 nullok use_first_pass > account sufficient /lib/security/pam_ldap.so account required pam_tcb.so shadow fork use_first_pass password required pam_passwdqc.so min=disabled,24,12,8,7 max=40 passphrase=3 match=4 similar=deny random=42 enforce=users retry=3 > password sufficient /lib/security/pam_ldap.so use_authtok password required pam_tcb.so use_authtok shadow fork prefix=$2a$ count=8 write_to=tcb use_first_pass > session optional /lib/security/pam_ldap.so session required pam_tcb.so session required /lib/security/pam_mkhomedir.so skel=/etc/skel.ru_RU.KOI8-R/ umask=0077 session required pam_limits.so

Вот мой вариант того же файла, который был чуть изменен в процессе исправлений. В остальных файлах все по описанию.

%PAM-1.0 auth sufficient /lib/security/pam_ldap.so auth required pam_tcb.so shadow fork prefix=$2a$ count=8 nullok use_first_pass account sufficient /lib/security/pam_ldap.so account required pam_tcb.so shadow fork use_first_pass #password required pam_passwdqc.so min=disabled,24,12,8,7 max=40 passphrase=3 match=4 similar=deny random=42 enforce=users retry=3 password sufficient /lib/security/pam_ldap.so # use_authtok password required pam_tcb.so shadow fork prefix=$2a$ count=8 write_to=tcb # use_authtok # use_first_pass session optional /lib/security/pam_ldap.so session required pam_tcb.so session required /lib/security/pam_mkhomedir.so skel=/etc/skel.ru_RU.KOI8-R/ umask=0077 session required pam_limits.so

Это относиться к первому варианту.

Заметьте, что создание домашних каталогов не работает с sshd из ALT Linux Master 2.4.

Возможно это будет работать (в Сизифе точно работает), если pam_mkhomedir вызывать на стадии account:

Эта строка должна быть первой (!), если account-строк несколько .

Теперь Вам необходимо отдельно настроить sshd (из-за того что он использует pam_userpass) и xscreensaver (из-за того что он использует <PAMROOT>/system-auth-user_first_pass)

Файл /etc/pam.d/sshd

#%PAM-1.0 auth required pam_userpass.so > auth sufficient pam_ldap.so use_first_pass auth required pam_tcb.so shadow fork prefix=$2a$ count=8 nullok nodelay blank_nolog use_first_pass auth required pam_nologin.so account include system-auth password include system-auth session include system-auth

Файл /etc/pam.d/system-auth-use_first_pass

#%PAM-1.0 > auth sufficient /lib/security/pam_ldap.so use_first_pass auth required pam_tcb.so shadow fork prefix=$2a$ count=8 nullok use_first_pass > password sufficient /lib/security/pam_ldap.so use_first_pass password required pam_tcb.so use_authtok shadow fork prefix=$2a$ count=8 write_to=tcb

Смена паролей в ldap

Замените Ваш /etc/pam.d/passwd на следующий файл.

#%PAM-1.0 auth sufficient /lib/security/pam_ldap.so account sufficient /lib/security/pam_ldap.so password required pam_passwdqc.so min=disabled,24,12,8,7 max=40 passphrase=3 match=4 similar=deny random=42 enforce=users retry=3 password sufficient /lib/security/pam_ldap.so

Заметьте, что если Вы не указали rootbinddn в файле /etc/ldap.conf или не создали файл /etc/ldap.secret (в Sisyphus он называется pam_ldap.secret),

содержащий пароль rootbinddn, то Вы не сможете менять пароли от пользователя root (вам прийдется ввести пароль пользователя для этого).

Однако, это не так страшно, если Вы используете ldapadd или gq для управления директорией с пользователями.

Примечание: если /etc/pam.d/passwd имеет следующий вид:

#%PAM-1.0 auth include system-auth account include system-auth password include system-auth session required pam_deny.so

то менять ничего не требуется – для изменения пароля будут иcпользованы настройки, сделанные в /etc/pam.d/system-auth.

Запускаем nscd

#chkconfig nscd on #service nscd start

Если при service nscd status он пишет что не запускается или тому подобное, то после исправления файла стоит останавливать сервис вручную, принудительно (например через top)

Есть еще один вариант конфигурирование файла nss_ldap (например для того чтобы избежать бруд-форс атаку), но в нем есть свои недочеты. Это касается того что рут, в консоли не может менять пароль пользователя из ЛДАП (возможно это связано с тем, что я менял файл system-auth), а все остальное может: passwd локального пользователя, su, id....

Для этого надо раскоменнтить в файле nss_ldap.conf строчку rootbinddb, занести сюда какого-нибудь пользователя, например cn=manager,dc=office,dc=etersoft,dc=ru. В файл /etc/ldap.secret записать пароль (mode 600, это для защиты)

Потом в slapd.conf в access to attrs=userPassword добавить by «cn=manager,dc=office,dc=etersoft,dc=ru» read. (это можно посмотреть в slapd который выше, т.к. там это уже есть)

Потом неплохо бы его добавить в лдап,

#user.ldif dn: cn=manager,dc=office,dc=etersoft,dc=ru objectClass: top objectClass: organizationalPerson cn: administrator

ldapadd ... (см. выше)

В случае, если использован будет первый вариант, то система будет менее безопасна, зато можно все менять.

Использование nss_ldap

NSS – диспетчер имен, расширение для glibc, позволяющее резолвить имена из разных источников (files, dns, nis, nisplus, ldap).

Для того, чтобы заставить его работать с nss_ldap, необходимо изменить /etc/nsswitch.conf следующим образом.

Замените обычные строки с passwd, shadow и group на эти.

#LDAP passwd: files ldap nisplus nis shadow: tcb ldap files nisplus nis group: files ldap nisplus nis

Примечание: Учтите, что если вы установите ldap в первым в списке, то некоторые статически слинкованные (rpm, sh, vi) программы будут выпадать с segfault.
