Hi, This is in continuation of my previous question. In stdconfig.py, following is mentioned. It says *cn=users *but users is an organizational unit. Then it should be* ou=users*? I am not able to figure out the corresponding LDIF for LDAP server? Why is it '*cn*' and not '*ou*' "rdnSchema": {67 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L67> "base": "dc=example,dc=com",68 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L68> "users": "cn=users",69 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L69> "groups": "cn=groups",70 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L70> "locations": "cn=locations",71 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L71> "resources": "cn=resources",72 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L72> "addresses": "cn=addresses",73 <https://trac.calendarserver.org/browser/CalendarServer/trunk/twistedcaldav/stdconfig.py#L73> }, What needs to be created on LDAP server to satisfy above rdnSchema expected by Caldav Server? Best Regards, PS: I have been struggling with this. Please provide assistance to resolve this issue?
