[ Reason ]
lemonldap-ng before version 2.0.15 has an issue that may maintain
a session active on a Lemonldap::NG's handler if user has a continuous
activity on this handler after session expiration or deletion
(CVE-2022-37186), if and only if user activity is tracked by handlers
(disabled by defaut)

[ Impact ]
Medium vulnerability

[ Tests ]
Test passed, non new tested backported here

[ Risks ]
No risk, patch is trivial

[ Checklist ]
  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

[ Changes ]
Handler's calls to session API now have a "nocache" option for writing.

Cheers,
Yadd
