as far as your login problems go, look up a user record on the Users tab and see if that record has any roles associated with it.
What roles needs to be associated?
you must also ensure that the user record you are trying to retrieve has permissions inside LDAP to look up itself and permission to look up the groups associated with it. the ACLs in slapd.conf govern that piece. you could use ldapsearch to "emulate" these searches by binding with the respective user's DN and passowrd and looking up its own details as well as its own groups.
I thought that this was ok since I can loggin to my linux account... (A while later) Ok. I just locked myself out :-) Great.
P.S.: LDAP and trying to use it for zope authentication can be very painful to set up if you're not experienced with LDAP first. there are a *lot* of factors and pitfalls involved. you must have a good understanding about how LDAP works, knowledge about LDAP schemas and LDAP ACLs.
Any suggestions of how to gain this knowledge? I know alot more now than I did a week ago, but I certainly need to learn more :-/ Thanks for taking the time explaining things! :) /Magnus
