Virtualmin doesn't store plain-text passwords at all - the only passwords=
kept for mail users is in the /etc/shadow file, which are one-way encryp=
ted and can never be decrypted.
Even the backup only contains encrypted passwords from /etc/shadow, which=
are written back to that file when restoring.

Subj: [webmin-l] Decrypt Virtualmin mail_users
Date: Wed 22 Mar 2006 6:44 pm
Dear Webmin / Virtualmin community,
We've been using Virtualmin to successfully manage our hosting process o=
n a variety of servers, we have a need to do a one time sync. of existing=
mail users in virtualmin to one of our other databases. Due to the sheer=
number of people using the service it isn't practical to request all use=
rs reset their password.
We noticed that when Virtualmin does a backup of the domains it hosts it=
includes information for each mail account, along with a seemingly encry=
pted password. As Virtualmin can restore backups it seems there is alread=
y the capability for it to decrypt the password from the mail_user's file=
We are looking for method to decrypt the password to it's original value=
, it can be an extension of Virtualmin or even a shell script.=20
Any help with this task is very much appreciated.
