First of all - PrincipalContext
only works against Active Directory, not against any other LDAP server.
Secondly: you're specifying invalid parameters for the constructor. Check out the MSDN docs on what constructors are available for PrincipalContext
.
You can define just a ContextType
parameter, in which case the PrincipalContext
is constructed against the current domain you're connected to:
var ctx = new PrincipalContext(ContextType.Domain);
Or you can use a constructor with a second string parameter which signifies the domain name of your domain (only the domain name - NOT a complete LDAP path!):
var ctx = new PrincipalContext(ContextType.Domain, "CompanyName.com");
Then you're connected to that specific domain, at the root level.
Or thirdly, you can specify a third parameter which defines the container in that domain to connect to:
var ctx = new PrincipalContext(ContextType.Domain, "CompanyName.com",
"CN=Users,DC=be,DC=ndl,DC=CompanyName,DC=com");
So you'll need to find the appropriate constructor and supply the correct parameters to get this to work - if you're using Active Directory.
