ocis-glauth fetches all users

[exalate-issue-sync]

solution as stated by [~jfd]:

1. konnectd uses an entryid, which is the fetched user dn, as the base dn

2. after checking that the search basedn, in this case the user dn, is in scope of the configured basedn glauth drops the search base dn and uses the configured one. the scope is base so the request should actually only fetch the single entry.

=> ocis-glauth needs to parse the search basedn and extract the userid so it can create the correct filter and only retrieve the requested account.
