The LDAP database has been hacked so the attacker has published the emails Names and also password hashes for all uses registered om https://identity.mageia.org

That may also include my identities there

The project has reacted by resetting all passwords.
This would mean that you cannot log in at Mageia anymore and must change/reset your password over there too.
The exciting part would be how this could happen....and nobody has a clue!

The very configuration of LDAP servers should prevent stuff like this.
So if you use your Mageia password here - CHANGE IT! ..and do the same on every other forum where you are using your Mageia password.
