I have some xerox printers looking in zimbra ldap as anonymous in version 5, after upgrade i have the following error message when trying to connect to zimbra ldap

[ERROR 34] Invalid DN syntax

I have used the command to get zimbra ldap user and password,
zmlocalconfig -s | grep ldap

zimbra_ldap_user = zimbra
zimbra_ldap_password = xxxxxxxxx

But keep getting this error, any sugestions how can o fix this?
