I found myself in a setup on where I need to enable some authentication method using mysql.

I already have an user scheme. That user scheme is working like a charm with MD5 password and CRYPT, but when I turn to SHA1sum it says:

[Fri Oct 26 00:03:20 2012] [error] Unsupported encryption type:
Sha1sum

No useful debug informations on log files.

This is my setup and some info:

debian6

apache and ssl installed packages:
