Problem changing passwords in 3.0.2

I am having some problems changing passwords in 3.02…as the subject
would suggest.

On a frest install, logging in as ‘root’ has no problems. Upon
changing the password, login fails with unkown user or incorrect
password. On creating a new user, logins are not possible either.

I tried creating a new user, changing the password via the root
user…same result. Looking at the data in the DB shows that the
password isn’t actually being changed. The encrypted blob is the same
before and after I try and change a users password.

All other functions seem to work okay.

Idea?
