Tracing an LDAP Problem
Use the following procedure to look for the problem.
To trace an LDAP problem:
1. Check the LDAP entries to ensure that all information is entered correctly.
2. Check the LDAP error logs for any hints.
3. Compare the entries to a current database entry.
4. Check the UIDs and GIDs of the LDAP entries. These IDs must be greater than 500 for the
ContentDirectors to recognize users and groups in the LDAP database.

inetorgperson
posixAccount

Joining a High Bandwidth ContentBridge to an LDAP Domain
Follow the procedures in this section in order.
NOTE:
In order to join a High Bandwidth ContentBridge to an LDAP domain, an LDAP or Open Directory
server must already be configured to serve as Samba Primary Domain Controller for the LDAP or Open
Directory domain.
NOTE:
It is not recommended that you switch between ActiveDirectory and LDAP once an authentication
method is chosen. Before continuing, make sure the High Bandwidth ContentBridge is not configured for
ActiveDirectory.
Creating a ContentBridge Account on the LDAP Server
NOTE:
This procedure is required for joining a High Bandwidth ContentBridge to an LDAP domain.
1. On the LDAP server, login as root.
2. Check whether the ContentBridge account with the hostname of the ContentBridge exists.
For example, for a High Bandwidth ContentBridge with a hostname of
hbcb205
:
[root@eng-ldap ~]# /var/lib/samba/sbin/smbldap-usershow hbcb205$
user hbcb205$ doesn't exist
NOTE:
Make sure to add "$" at the end of the ContentBridge hostname.
3. Create a local user account with the host name of the ContentBridge. For example, for a High
Bandwidth ContentBridge with hostname
hbcb205
:
[root@eng-ldap ~]# adduser hbcb205
