[Lizmap] More verbose logging for LDAP

[Paolo Cavallini]

Hi all,
some LDAP users cannot authenticate on our system. Apparently everything
is fine, as LDAP server records the access and returns the
authentication, therefore auth.log does not report an error (it does
when an user insert wrong credentials).
We cannot find a reason for this: would it be possible to enable fully
verbose auth logging, to search for the issue?). Any other suggestion?
Thanks a lot.
