failed to bind to ldap server

I have ldap installed and the ldap search commands work pretty good. But when trying to admin it through webmin i get this error.

Failed to bind to LDAP server as : No password, did you mean noauth or anonymous ?. Maybe your module configuration is incorrect.

Although all ldapsearches work , i can't adminstrate it with webmin
So i don't think it's my slap.conf, but still.
This is my slap.conf without some of the comments

Probably you used "Manager" oder "cn=Manager" als the Login-Name. This is not correct. In Webmin you need to use the whole DN like "cn=manager,dc=bahadoer,dc=nl" for the login.

Thank you, Arknius.

But where should I change this login name??? in slapd.conf???

Edit : I found 2 errors in my slapd.conf

HOST 192.168.1.1
BASE dc=bahadoer,dc=nl

These Directives are not right. I commented them by putting # before the lines.

But now i have a different error :

Failed to connect to LDAP server port 389

I'm guessing that it has something to do with TLS connections, can somebody confirm this? What does this do and how can I correct this?
