Problem: Using udm gives an 'authentication error: Authentication failed'

Problem:

Using udm gives an ‘authentication error: Authentication failed’

~# udm list
authentication error: Authentication failed

Environment:

This happens on a slave server!

Investigation:

/var/log/univention/directory-manager-cmd.log

On a slave server the machine account is normally used for bind, but here the cn=admin account is used.

Solution:

Make sure there is no ldap.secret on the server:

~# ls -l /etc/ldap.secret
-rw-r----- 1 root DC Backup Hosts 6 Sep 12  2016 /etc/ldap.secret

If there is one, you have to delete this. This is not “allowed” on a slave server.
