I have got some wireshark captures, and it shows that it is UDP. But in theory it says that it uses both TCP and UDP. So I m confused. And what is the difference b/w LDAP and CLDAP? Are they both UDP protocols?
Normally LDAP is a TCP protocol. But Microsoft uses LDAP also over UDP. See here: http://msdn.microsoft.com/en-us/library/cc717362(v=prot.10).aspx
So it is both.
