The scheduled task to sync LDAP users is failing with below error:


Execute scheduled task: LDAP users sync job (auth_ldap\task\sync_task)
... started 15:37:54. Current memory use 8.9MB.
Connecting to LDAP server...
Creating temporary table tmp_extuser
Did not get any users from LDAP -- error? -- exiting

Fatal error:  Uncaught coding_exception: Coding error detected, it must be fixed by a programmer: A lock was created but not released at:
C:\inetpub\wwwroot\lib\cronlib.php on line 279

 Code should look like:

 $factory = \core\lock\lock_config::get_lock_factory('type');
 $lock = $factory->get_lock(Resource id #507);
 $lock->release();  // Locks must ALWAYS be released like this.

 in C:\inetpub\wwwroot\lib\classes\lock\lock.php:117
Stack trace:
#0 [internal function]: core\lock\lock->__destruct()

Environment:

  • Windows Server 2012 R2
  • IIS 8

I'm stumped at what could be causing the error, can anyone help?

We have the same problem.

Any solution?

The same with LDAP (sync plus).

Yes we managed to get this fixed, it turns out I had specified "User Lookup settings > Contexts" and "User Lookup settings > Object Class" incorrectly


I had pointed "Contexts" to a security group,  and left "Object Class" blank.


To get it working:


"Contexts" was pointed to the users OU

ou=users,ou=uk,dc=contoso,dc=local


"Object Class" was specified as the security group that my Moodle users were in (full query string below)

((&(objectCategory=Person)(sAMAccountName=*)(memberOf=cn=moodle_users,ou=security groups,ou=groups,ou=uk,dc=contoso,dc=local))
