      Description

      Hi

      I migrated from 1.9.4 moodle to 2.1.1+ and using Openldap to import users appears this error. It's more similar to other issue (number 24666) but it's closed.

      When I syncronize appears:
      Database transaction aborted automatically in /usr/share/moodle/auth/ldap/cli/sync_users.php
      Default exception handler: Error writing to database Debug: Duplicate entry '3-joan@admi.escola.es' for key 'user_mneuse_uix'
      INSERT INTO user (firstname,lastname,email,idnumber,username,confirmed,auth,mnethostid,lang) VALUES(?,?,?,?,?,?,?,?,?)
      [array (
      0 => 'Joan',
      1 => 'Escola',
      2 => 'joan@admi.escola.es',
      3 => '00265',
      4 => 'joan@admi.escola.es',
      5 => 1,
      6 => 'ldap',
      7 => '3',
      8 => 'en',
      )]

      !!! Error writing to database !!!
      Potential coding error - existing temptables found when disposing database. Must be dropped!
