For security reasons we recommend to create a '''simple authentication user''', which can read LDAP entries, but is not able to login to any service provided.

== Create a User with LDAP read permission ==
First create a new user using the UMC by opening the Users module and then using the "Add" button. Click on '''Advanced''' in the new window.

Fill out all neccessary text fields (lastname, username and a safety password) and go to the "'''Option'''" tab. Untag all checkboxes except "'''simple authentication'''".

== Test commands ==
With the following shell command you can check if the created user is able to read the LDAP entries:
ldapsearch -x -D uid=<LDAP user>,cn=users,$(/usr/sbin/uct get ldap/base) -W uid=Administrator
and enter the password of the LDAP search user. If you can see the Administrator's user object the search user is configured correctly and can be used in services to query the LDAP.
== LDAP attributes and values ==
{| class="wikitable"
! attribute                                          !! values !! command
| ldap hostname || <ip of the server> or <FQDN of the server>  || hostname -f
| ldap port || 7389 or 7636 for SSL
| ldap method || plain
| ldap base || output from 'ucr get ldap/base'
| ldap uid || uid
| ldap bind dn || DN of your LDAP search user || {{!}}  univention-ldapsearch uid=<username of your LDAP search user>  | grep ^dn
| ldap password || <password of your LDAP search user>
| ldap filter || objectClass=person
| user DN || cn=users,<LDAP base> || ucr get ldap/base
| group DN ||  cn=groups,<LDAP base> || ucr get ldap/base
| group filter || objectClass=univentionGroup
| group attribute || cn
== Troubleshooting ==
Possible error messages may appear:
> (ldap) Authentication failure! invalid_credentials encountered.
Solution: Check, with the following command, if your bind user (LDAP search user) has enough credentials to search through the LDAP entries.
univention-ldapsearch -D <DN of your user> -W
If you receive no error message , so check your entries in the configuration of the LDAP plugin. Otherwise, try to work through these wiki article again.
Another error message could be:
> (ldap) Authentication failure! ldap_error: Net::LDAP::Error, Connection reset by peer - SSL_connect
Solution: This error message can have several causes. One of the common reason is, that the port number has been set incorrectly.
* LDAP Port: 7389
* LDAP Port (SSL):  7636
