Login Issues at QPWDLVL 2 for some users

["daveML@xxxxxxxxxxxx" <daveML@xxxxxxxxxxxx>]

Hi All,
We recently moved from level 0 to level 2 on our password complexity.  In 
large part we did this to allow our users to have matching passwords on the 
i5 and Windows (where we have some fairly strict rules for PCI reasons).
Anyhow, it seemed to go well.  We had to talk a lot of people through 
changing their i5 passwords to mixed case, since at level 0 they are 
actually stored as lower case.  A little painful, but overall not too bad.
Today though, we have an issue that seems to affect approximately half of 
our user base.  They cannot login on QDSIGNON2 with their new passwords.  
If entered on the iSeries Access logon popup they are fine, but not on the 
green screen.  I have personally verified it does not work for some users 
and the passwords are being typed correctly.
Works fine for me and some others, but not all.  I even tried copying my 
usrprf to a new user and that user -- even with my identical password and 
settings -- still gets the error:CPF1107 - Password not correct for user 
profile. 
Has anyone else seen anything similar?  We are at V7.1 with latest groups.

Thanks!Dave
