I configured ABxLDAP to sync with my account on the LDAPBook at entic.net.
I also sync all my contacts with Mobileme.
I have 600 contacts and it failed after transferring 60.
Anil at entic.net informs me that the error message was the following. I'm not a programmer and cannot help him.
Anil says:
"15/Jul/2010:15:17:41 -0700] MODIFY RES conn=460930 op=2 msgID=3 result=65 message="Object class orgPerson cannot be added to entry cn=Amanda Sowa,uid=alexmathew,ou=People,o=entic.net because that class is not defined in the Directory Server schema" etime=16

That's the error it bombed with... I think. There were a few errors about it existing on the server already also.
Does abxldap actually have this objectclass, orgPerson?"

Any ideas and can you try to sync with the LDAP server at entic.net on your end and let me know if there is something else I should do?

Thanks

Could you please post a screen shot of that contact with all the nodes expanded using Address Book 4 LDAP (see Application folder) as well as your System Preference configuration.
