[wp-testers] wp 2.5.rc1 causes passwords to break on pre 2.5 releases using shared user table

[Jeff Sherk Forerunner Ministries]

I posted this problem here:
http://wordpress.org/support/topic/163529

Is there a specific place to make bug reports?

Here's the issue...

I have 5 production installs of WP 2.3.3 on my host, and have installed 
v2.5.RC1 in my sandbox on the same host. They all share a common user 
table for the user names and passwords.

I can no longer log into my 2.3.3 blogs using any user that has logged 
into 2.5.rc1... it gives a password incorrect error.

I have to physically go into the database and change the md5 password to 
something else in order to able to log back into the 2.3.3 blogs. It 
will then work fine again, until I use that username to login to the 
2.5.rc1 blog, and then it no longer works again on the 2.3.3 blogs.

I noticed that the problem occurs because when I log into 2.5.rc1 it 
actually CHANGES the password in the database!!!

Since I only have this installed in my sandbox, I just temporarily 
switched it back to using it's own user table instead of the shared one.

Anybody know why it's doing this? It may not be an issue if all your 
blogs that share the user table are all updated at the same time, but 
I'm not sure.
