c# - Why is User.Invoke("SetPassword") using my computer's current credentials and how I can I specify them instead? -

i able create new users in remote activedirectory server, doing using admin account on server. how that:

string connection = "ldap://serveraddress/ou=newusers,ou=people,dc=mydomain,dc=local"; usersdirectoryentry = new directoryentry(connection, "adminusername","adminpass"); directoryentry newuser = usersdirectoryentry.children.add(userstring, "user"); newuser.commitchanges(); 

however, after trying set password using:

updatepassword(newuser, "userpasswordmeetsrequirements"); 

where

private static void updatepassword(directoryentry user, string password) {     user.properties["pwdlastset"].value = -1;     user.invoke("setpassword", new object[] { password.trim() });     user.properties["useraccountcontrol"].value = 0x0200 | 0x10000;     user.commitchanges(); } 

where user of type directoryentry (https://msdn.microsoft.com/en-us/library/system.directoryservices.directoryentry(v=vs.110).aspx)

and on user.invoke line system.reflection.targetinvocationexception --> system.unauthorizedaccessexception: access denied.

that admin user should indeed have set password permissions. after looking in ad logs found @ user.invoke line program trying connect ad server using current credentials on computer (which on different domain).

why happening, , how can force use admin account used user creation?

are passing newuser object updatepassword? assume it's using same credentials.

but if not, can create new object this:

var user = new directoryentry(newuser.path, "adminusername","adminpass"); updatepassword(user, somepassword);
