I recently did a bit of work to make a nice little AJAX/DHTML user picker for SiteBuilder2. It is basically an in page popup that allows quick searching of Warwick users by first and last names to find their usercode. This is useful for helping people work out usercodes for permissions and properties pages and such.
One problem was that it was a touch slow, especially for very broad searches such as everyone with a first name starting with K and last name starting with S.
In LDAP terms, we were doing the following:
This works just fine and always used to return around 300 users. However, we always had to check for any expired accounts after the results were returned. Because account expiry was not very well populated in the past, only a few out of those 300 would be filtered out. However, after the recent tidying up of the directory due to password resets there are now many many more disabled accounts in NDS (our directory), which is a good thing. Now we can do this:
NamingEnumeration searchAnswer = ctx.search("o=Warwick", "(&(givenName=K*)(sn=S*))", sctls);
So only people matching the first name and last name searches who also do not have a logindisabled attribute. This now returns just 97 results and is around twice as fast meaning out user picker searches should be much faster from now on.
NamingEnumeration searchAnswer = ctx.search("o=Warwick", "(&(givenName=K*)(sn=S*)(!(logindisabled=*)))", sctls);
