How to Set the "password must be changed upon next login" attribute (LDAP provider) of the AD user)

Recently, a test environment is required for training customers. Because the system uses domain user verification, it takes a lot of effort to establish a large number of Domain Users, in addition, the user name in the test environment can be set up according to the user organization and role, for example, role. unit

Therefore, using C # To create users in batches, we found two difficult problems:
1. How to set the initial password of the user name
2. How to Set "Change Password Upon next login" not selected (selected by default)

The final test establishes the user's Code As follows: 1 Directoryentry ad =   New Directoryentry ( " LDAP: // dc = cnblogs, Dc = com " , " Administrator " , " PA $ word " , Authenticationtypes. Secure );
2 Directorysearcher searcher =   New Directorysearcher (AD );
3 Searcher. Filter = String. Format ( " Ou = {0} " , " Blogs " );
4 Searchresult result = Searcher. findone ();
5 If (Result ! = Null )
6 {
7 String Samaccountname =   " Tester " ;
8 String Displayname =   " Test Creation " ;
9 Directoryentry userentry = Result. getdirectoryentry (). Children. Add (string. Format ( " CN = {0} " , Samaccountname ), " User " );
10 Userentry. properties [ " Samaccountname " ]. Add (samaccountname );
11 Userentry. properties [ " Displayname " ]. Add (displayname );
12 Userentry. properties [ " Userpassword " ]. Add ( " PA $ word " );
13 Userentry. properties [ " Useraccountcontrol " ]. Value =   544 ;
14 Userentry. properties [ " Pwdlastset " ]. Value =   - 1 ;
15 Userentry. commitchanges ();
16 Userentry. Invoke ( " Setpassword " , New   Object [] { " PA $ word " });
17 }

Note:
1. userentry. Invoke ("setpassword", new object [] {"pa $ word"}); must be called after userentry. commitchanges;
2. userentry. properties ["pwdlastset"]. value =-1; Set "the user must change the password upon next login" to be deselected. Refer to the link below.
