I am getting the following error while trying to get CIFS going on an OES2

CRITICAL: AUTH: Failed to fetch credentials of User : cn=user,OU=ou,O=o
Nmasldap-error : -1659 , ProxyUser- cn=cifsProxyUser-FSGate,o=servers .
Check Configuration

I am guessing the cifs proxy user does not have enough eDir rights
somewhere, but I am unsure on how to fix this if this is the case.

Any ideas ?
