      Description

      We are using Waffle for SSO in combination with the LDAP Authenticator on XWiki 9.11.8

      After updating the Authenticator to version 9.3.3 we get random error messages when calling XWiki especially after it was idle for some time.

      The user seems to be empty at first call. Reloading the page solves the problem but the user experience is drastically degraded.

      After downgrading to Authenticator 9.3.2 everything ist OK again.

      See enclosed text file for complete error log message.
