LDAP Getting Full user Name C++

Question

I'm writing a little Application at my Office. In this Application i have to get the full UserName. It's written in Qt / C++

I like to get this Information over LDAP. Now i can connect to our Active Directory Server and can connect to the Search function.

This information is from an example written by Microsoft.

But at this Point the Example confuses me. I Don't get it how i can give this Server an Username and receive the Full Name.

Link to the Microsoft example: http://msdn.microsoft.com/en-us/library/windows/desktop/aa367016(v=vs.85).aspx

Can someone give me an Advice how i can get this Information?

Thanks and With best regards Chris ;)

P.S. Sorry for the bad English. P.S.S and if i missed Something or you need more Information just say it.

Answer 1

It appears that you are requesting the cn or commonName, sometimes the value of that attribute is the full name. If it is not, try adding givenName and sn to the list of requested attributes. givenName is the first name sn is the surname or last name.
