Dear Everyone, We have get a social institute's linux system to manage for two months ago from another IT company. Unfortunately we haven't got any documentation about it. Now one of our client's user phoned us, that she cannot authenticate in the mail system with the info user. They use Axigen mail system. I found that in the error log there are a lot of messages for the corresponding error: sasl_server_step error: 'SASL(-13): authentication failure: incorrect digest response' That was the first one. Than i found a lot of other, told me that info users password was incorrect. Also found some other: Authentication error [info]: Wrong SASL step Only one message after a few unsuccessfull login attempts: The client made 5 errors. We reject it! I tried the following: restarting saslauthd and axigen service Editing the config axigen.cfg to let more authentication attempts then restarting axigen service again. I also tried to change the user's pass with saslpasswd2 command which was successfull but the system was not accept the new pass and write another authentication failure "invalid password". Webmail and Thunderbird also not working with this mailbox, but every other still goes without errors. I don't know now what to do next, please help!!!
