We're having the same problem; running version 13.4.5603;
There was a problem on the server, and after the reboot we lost 13 email-pwd;
the problem is, I am not able to reset the password, as it is not saved anymore;
how should this be done?
Which possibility is there to avoid this in the future? (it already happend three times! never had it before on older version, on an older server); this one is using a virtual hosting system;
I found out how to reset the lost user data; there is a userdata-bak-file in the user's directory; the right userdata-config files is a file full of empty data; the bak is a readable xml-file; if I rename the bak-file to the cfg-file, the lost userdata and userpwd and userconfig is restored! at least this is good news!!!
You don't even have to stop and restart the service
