Redmine

In Short:

How can i change Redmine or its settings to modify the data send to LDAP?

I want to remove the MyDomain.de from the following line stated by LDAP:

[05/Jan/2016 10:08:12] LDAP: User cn=000000e1,fn=Contacts,fn=public,fn=ContactRoot@MyDomain.de doesn't exist. Attempt from IP address 192.168.1.68.

The settings for the Base DN in Redmine are:

fn=Contacts,fn=public,fn=ContactRoot

In Long:

I set up a new Redmine 3.2.0 onto a CentOS 7 machine. Then i imported the uploaded files and sql data of an older Redmine into the new Redmine.

Except for the plugins everything seem to be ported.

I have a Kerio Connect Client running, which handles the login data of the users. The settings in the administration section are the same as in the old Redmine, since they were ported. The problem that now arises is that i can not login with those LDAP users.

I did not set up the old Redmine, but the one who set it up modified something to make it work ... unfortunately he did not write it down...

I had a look in the Logfiles from the old and new Redmine, both are identical in what they logged for the send data to LDAP.

In the LDAP the following error is stated:

[05/Jan/2016 10:08:12] LDAP: User cn=000000e1,fn=Contacts,fn=public,fn=ContactRoot@MyDomain.de doesn't exist. Attempt from IP address 192.168.1.68.

The problem seems to be the MyDomain.de. The LDAP does not expect this and therefore refuses the login. The settings for the Base DN in Redmine are:

fn=Contacts,fn=public,fn=ContactRoot

I have none experience with Redmine and LDAP, so has anyone a tip for me how to change this?
