Horde Password Reset Problem

[Vooservers]

Hi,
I am running Plesk 9.5.2 and I am having problems when users are trying to reset their passwords from within Horde. It will work perfectly fine if I specify a new password that has never been used before however if I specify a password which has previously been used it will come up with the following error:

Failure in changing password for poppassd server: 500 Incorrect Password.

I presumed that this may be due to a password policy on the server so I checked the local security policy and the password history option is disabled. I have also checked mail enable and I could not see any sign of a password policy there. Has anyone else seen this problem or now something that may be causing it?

Thanks in advance.

Did you tried this already published workaround?

Thanks for the link. I gave this workaround a try yesterday morning however it doesn't seem to have fixed the problem I am experiencing.
