HEEEEEELP, Suddenly mail server go crazy, dont authenticate the users, any user, saying its a login error but even when I change the pass, its still happends, I dont know what can be the problem!! any idea?????? PLEASE ITS URGENT!
More data, I found the error but I don't know why happens, all the passwords in the shadow file gone blank. I revered from a backup and now I have less error, although I still have in one domain in particular, the problem seems to solve changing the pass. Any one have any idea why this happen?
Thanks till I did it and now all seems to be ok, but I still dont know why this happened to prevent will happen again. Anyone have an idea?
