"Temporary authentication failure" ? Cant connect with ldap user

[David Scheele]

The ldap-utils were already installed.
I did the ldapsearch you gave me, but after inputting my admin password it
gives me
*ldap_bind: Invalid credentials (49)*
I logged into the ldap server with my admin credentials (which worked fine)
and changed my password to '12345', Trying that, still *Invalid credentials*
.

1.) I tried that already. The error switches to syntax error then.
2.) Not really. An upper case letter and a number + various lowercase
letters. Not very exotic.

Is the pass_filter neccessary? I just wanted to make the installation as
basic as possible, to not get any unwanted errors.

Best,
David
