      0/ enable full debug
      1/ set up ldap enrol where one user gets different roles in different courses
      2/ login as that user
      3/ review error log and verify user was enrolled properly
      4/ add a lot more enrolments for that user and test if ldap paging works during login (you might want to lower the paging limit in enrol settings)

      Description

      The trouble is that 

      protected function find_ext_enrolments ($ldapconnection, $memberuid, $role)

      closes connection and creates a new one, but the calling code continues to be using the CLOSED connection!

      PHP Warning: ldap_control_paged_result(): 90 is not a valid ldap link resource in moodle25/enrol/ldap/lib.php on line 732

      This may result in user unenrolment causing major data loss...
