      Description

      For the REST API we use the USERID "build". The LDAP Authenticator 9.2.6 is working rather well, but we've got this message in the log :

      Despite this message of error the REST operations are successfull.
      If y delete the user from the users in XWiki, this error desappear.
      This problem might hide bigger problems relatives to LDAP Authenticator.
