Using LDAP Provider to retrieve First Name and Last Name

[Prasad Karunakaran]

I am using the C# DirectoryEntry class to retrieve the Properties of
an user object in the Active Directory. I need to get the First Name
and Last Name as properties. I know it is not supported with the ADSI
NT Provider and only supported in the LDAP Provider.

So given an UserId (UID) how can I read the First Name and Last Name
using LDAP Provider. If anybody can help me with a C# sample code it
would of great help.

Thanks in advance.

regards,

Prasad

You might want to check out my ADSI browser "BeaverTail" - it will
show you your AD objects, and their properties, with the corresponding
LDAP attribute names.

As for first and last name, you'd have to use the LDAP properties
"givenName" (first name), and "sn" (for surname = last name) to grab
those values:

DirectoryEntry deUser = new
DirectoryEntry("LDAP://cn=YourUser,cn=Users,dc=YourCompany,dc=com");

if(deUser != null)
{
string sFirstName =
deUser.Properties["givenName"].Value.ToString();

string sLastName = deUser.Propeties["sn"].Value.ToString();
}

Mind you - you might want to wrap those calls into some error handling
code, since if your user for some reason doesn't have a first name or
last name attribute value set, those calls will crash (since the
deUser.Properties["sn"] will be null, if the "sn" attribute is not
set).
