I did, yes.  However, it didn't output plain text, so I didn't
go hunting as to what format I was seeing.  The "password
mismatch" seemed to point to Squirrelmail, so I moved on towards
that angle.  I'll decode it and see what's actually happening to
the password, that might help track down the issue.

I did do some searching in the archives before asking, but I'll
certainly go back and do some more exhaustive searching.

Thank you for all your help, Timo, it's greatly appreciated!
