[CalendarServer-users] what LDAP schema includes loginEnabled ?

Code and plist references loginEnabled attribute but I can't see that as a part of any of my schema files on my LDAP server? Is this a 'new' apple.schema attribute for Lion or is there a schema I'm missing? I currently use the following schema: core.schema collective.schema corba.schema cosine.schema duaconf.schema inetorgperson.schema java.schema misc.schema nis.schema openldap.schema kerberos.schema apple_auxiliary.schema samba.schema apple.schema (modified as per common modification needs for apple schemas on linux ldap) Rob
