 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!!!

 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.

 I posted this problem here:
