[Samba] samba upgrade, now macs can't connect

[Jay G. Scott]

machine A:  samba server, upgraded from 3.0.7 to  3.0.22.
solaris 9.

machine B:  samba client, on powermac G4, OS 10.4 (i believe).
i think samba is 3.0.10.

after the upgrade of the samba server (A), machine B cannot
get onto A.  it keeps saying the password is wrong.

i've tried tons of stuff.  the keychain has been reset.  the
client has been rebooted.  the server has had samba restarted.
i've tried 3.0.22, 3.0.24 compiled w/ ldap, and 3.0.24 compiled
w/o ldap.  all do the same thing.

from ANOTHER mac (machine C), the same user from B __can__ get in.

is there some cache on machine B i need to clear?  it seems like
it would have to be a file, since it survives reboot.

thanks for any suggs.
