У меня есть открытый сервер LDAP:
IP: 192.168.0.70 (dell)
DIT:
(видно через ldapphpadmin)
И для Патрисии Дучешне
dn cn=patricia duchesne,ou=users,dc=memorandum,dc=pro
cn patricia duchesne
gidnumber 501
givenname patricia
homedirectory /home/users/pduchesne
loginshell /bin/bash
objectclass inetOrgPerson | posixAccount | top
sn duchesne
uid pduchesne
uidnumber 1000
userpassword {MD5}eFI0F0...
Тогда у меня есть клиент LDAP:
IP: 192.168.0.60 (пб)
NSSWitch настроен:
$cat /etc/nsswitch.conf
passwd: files ldap
group: files ldap
shadow: files ldap
gshadow: files
hosts: files mdns4_minimal [NOTFOUND=return] dns
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
также как и ldap-auth:
$ cat /etc/auth-client-config/profile.d/ldap-auth-config
[lac_ldap]
nss_passwd=passwd: files ldap
nss_group=group: files ldap
nss_shadow=shadow: files ldap
nss_netgroup=netgroup: nis
и libnss:
$ cat /etc/libnss-ldap.conf
uri ldap://192.168.0.70
base dc=memorandum,dc=pro
Я могу получить информацию о пользователе ldap:
$ getent passwd | tail -n 1
pduchesne:*:1000:501:patricia duchesne:/home/users/pduchesne:/bin/bash
Но я не могу подключиться:
С IP: 192.168.0.80
$ ssh pduchesne@192.168.0.60
pduchesne@192.168.0.60's password:
Permission denied, please try again.
pduchesne@192.168.0.60's password:
Permission denied, please try again.
pduchesne@192.168.0.60's password:
Permission denied (publickey,password).
Что мне не хватает?
Я просмотрел сотни веб-страниц, не найдя способа настроить все это :(https://help.ubuntu.com/community/LDAPClientAuthentication https://askubuntu.com/questions/127389/how-to-configure-ubuntu- as-an-ldap-клиент https://www.digitalocean.com/community/tutorials/how-to-authenticate-client-computers-using-ldap-on-an-ubuntu-12-04-vps
Поиск этой страницы: https://www.vincentliefooghe.net/content/openldap-gestion-des-logs Я понял, что не знаю, где находятся журналы ldap :-(

Добавление пользовательского хеша pwd на сервере ldap (см. Дамп пользователя в начале)

Следуя предложению @grawity, я установил libpam-ldapd:
romain@pb$ sudo apt-get install libpam-ldapd
[sudo] password for romain:
LDAP Password:
The following packages were automatically installed and are no longer required:
auth-client-config ldap-auth-config
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
libpam-ldap
The following NEW packages will be installed:
libpam-ldapd
Do you want to continue? [Y/n] Y
(...)
Setting up libpam-ldapd:amd64 (0.9.6-3) ...
Затем я настроил /etc/nslcd.conf в котором, как я заметил, не указывалось, как правильно использовать ldap version3 (я не знаю, какая версия по умолчанию? ):
romain@pb$ sudo cat /etc/nslcd.conf | grep "^[^#]"
uid nslcd
gid nslcd
uri ldap://192.168.0.70
base dc=memorandum,dc=pro
ldap_version 3
tls_cacertfile /etc/ssl/certs/ca-certificates.crt
Перезапущен nslcd:
romain@pb$ sudo service nslcd restart
и попытался подключиться с моего Mac:
romain@Mac:~$ ssh pduchesne@pb
который работал ... вроде:
romain@Mac:~$ ssh pduchesne@pb
pduchesne@pb's password:

Новый вопрос (для редактирования 4)
Почему я не меняю пользователя? Я ожидал войти в 'pb' как 'pduchesne':-/
Старый вопрос (до правки 4)
Я не знаю, какие файлы проверять - любые советы приветствуются.
