Hello again! The calendar server I've been installing on RHEL 6 is mostly working now, but I'm still struggling to configure the server to work with LDAP in the manner which I need. In the application that I'm writing, we have several resources that the users will be scheduling time on actual machinery and these machines are resources listed in LDAP. I took some time to read through the ConfigureLDAP article on the wiki, but now my server doesn't seem to want to load the resources properly from LDAP. First off, from what I can understand from the iCal and caldav specs is that there are 4? types of principals. Users, Groups, Resources, and Locations. Users and groups have the ability to schedule a resource at a location. Once the resource is scheduled at a certain time, no other person should be allowed to double book that resource correct? If this assumption is true then this is exactly what we need. :) So here is the difficulty I face. Using my limited understanding of LDAP and DCS I have not been able to produce a configuration file that even works right now. My goal is to pull the Users, Groups, and Resources from LDAP and the following is the path (is path the right word?) to each of these. Users - cn=users,dc=example,dc=base,dc=path Groups - groupCategory=instruments,dc=example,dc=base,dc=path (where membership in the group is defined by the memberUid attribute for each of the results returned) Resources - groupCategory=instruments,dc=example,dc=base,dc=path (where this is all of the resources) But this doesn't return any results when I try to browse to the :8008/principals/groups/ so it makes me think that I have the ldap parts improperly configured. Since I don't want the actual config to take up too much room, I have it pasted in a pastebin right here: http://pastebin.com/GnbEG0KM In summary, with my current configuration, DCS lists 0 groups and 0 resources, and I need help figuring out how to make the configuration work so that each of the instruments listed in groupCategory=instruments is both a group (with membership defined as people in the memberUid field) and each of the groupCategory=instruments is a resource. Any help is greatly appreciated! James
