UserPrincipal
's FindByIdentity
method allows me to search ActiveDirectory using username.
However, I also want to be able to search using user's real name (e.g. Wayne, Bruce)
How can I do this?
You can use a PrincipalSearcher
and a "query-by-example" principal to do your searching:
// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// define a "query-by-example" principal - here, we search for a UserPrincipal
// and with the first name (GivenName) of "Bruce"
UserPrincipal qbeUser = new UserPrincipal(ctx);
qbeUser.GivenName = "Bruce";
// create your principal searcher passing in the QBE principal
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);
// find all matches
foreach(var found in srch.FindAll())
{
// do whatever here - "found" is of type "Principal" - it could be user, group, computer.....
}
If you haven't already - absolutely read the MSDN article Managing Directory Security Principals in the .NET Framework 3.5 which shows nicely how to make the best use of the new features in System.DirectoryServices.AccountManagement
Update:
Of course, depending on your need, you might want to specify other properties on that "query-by-example" user principal you create:
Surname
(or last name)DisplayName
(typically: first name + space + last name)SAM Account Name
- your Windows/AD account nameUser Principal Name
- your "[email protected]" style nameYou can specify any of the properties on the UserPrincipal
and use those as "query-by-example" for your PrincipalSearcher
.
