I saw that on my system Jared and didn't really understand it but I am sure I
have head or read something that it is to do with migrating users.
I am happy to be corrected on the matter by anybody who knows better than me
(which won't be that difficult)
John

Jared,
I understood that the old style password hash was there to support a database
which has been migrated from 10g to 11g and converted to use the new case
sensitive passwords.
As an ex 10g user changes his password or has an alter user command run against
him he changes from the old hash to the new hash (which also includes case
sensitivity) which is the reason why there is room to accommodate both hash
versions.
I don't claim to know exactly why the hash and sha1 passwords are both included
in
sys.user$, but that doesn't seem to fit the bill.
on an 11.1.0.7 database
