A query over all users returns just 100 users.
Why a query over all users returns just 100 results, when I have much more users in LDAP?
A user searchlimit exists. Per default this limit is 100. This has performance reasons. But it could be overloaded in the LDAP provider settings. When you add a property "user.search.Countlimit" with a higher value. You will get more results.
NOTE: If the value is to high, everytime a lot of users are returned. This could lead to performance problems.
