LDAP Warning upon first time login

when our users login into piwik for the first time, they get this warning message

WARNING: UserMapper::getPiwikPasswordForLdapUser: Could not find LDAP password for user ‘gmichaud’, generating random one.

But this wont happen the second time they login. Any idea why?
We are currently using LoginLdap (v3.2.1)

Hi there,

The password is generated once and then stored. If you have an issue with LDAP or find a bug, please create a report on the LDAP bug tracker: Issues · matomo-org/plugin-LoginLdap · GitHub

Is this behaviour normal? I mean to ask if this is a bug or not?
