How do I change Dovecot user passwords stored in a database?

Question

I have a setup running AuthDatabse configuration. All works fine from a webmail side, but if I want to use doveadm to change the user password, the database is not affected.

Any clue?

Answer 1

doveadm cannot be used to change user passwords, you have to do this through some other system.

• doveadm user can only look up user information
• doveadm auth can be used to verify credentials
• doveadm pw calculates password hashes for different schemes, but does not apply any changes

doveadm pw -u [username] is only used and required for Digest-MD5:

-u user

When the DIGEST-MD5 scheme is used, also the user name must be given, because the user name is a part of the generated hash. For more information about Digest-MD5 please read also: http://wiki2.dovecot.org/Authentication/Mechanisms/DigestMD5
