Hi,

LDAP searches in general can be customized, however it really depends on what your trying to customize it to of course.

I've used the DominoComms Directory application for this as it consolidates unlimited CUCM clusters and LDAP servers into a single "CallManager" feel directory structure on the phone. It provides the ability to modify the telephone numbers as well before displaying, so in the AD it has Belgium numbers like +321 XXXXXXX which then I run through the DominoComms filter and it then displays 732XXXX which is the internal short code to that office. Works in reverse as well for offsite locations and also allows different LDAP security zones (i.e. CXO's can have access to other CXO access home records etc). It's now deployed to 3 world regions and works well. The guys there seem quite helpful and have added a few specials for me without extra cost so could be a good and quick way to solve your problem. I believe the link is http://www.dominocomms.com/dcproducts.php?page=multidir
Hope this helps

Hi,
 
I'm pretty sure that it will run on most web servers. I've only used it on Apache but I suggest that you email them direct to ask (also ensure it meets your business needs etc). I've dealt with Jeff at DominoComms, his email is jeff@dominocomms.com (probably could have guessed that!)
 
Hope that helps.
