Get PhoneNumber from Ldap or from MySQL ?
 

Hello,

what would be less stressing for a server : polling the server for a Name + Phonenumber to a MySQL-DB or a Ldap-directory ?

I have a Centos5.5 server with Ldap and MySQL. Where would I put (and query) this information ?

well ldap generally, but there could be all sorts of things going on behind the scenes. How often are you planning on doing this? Requesting a phone number should be childsplay and if that's a concern about load, you've got real problems.
