NW 6.5 SP2
AFPTCP (build 288 SP) v2.01.13 - May 14, '04
NMAS v2.68 - June 16, '04

The upgrade to 6.5sp2 was only recent. At this time OS X.3.x users can
only authenticate when cleartext is enabled. Even after a successful AFP
login, if we return to encrypted, users cannot login. Prior to update from
NW6, simple passwords worked both ways.

I have done searching in this forum and see that a backrev of AFPTCP seems
pretty promising. I am also reading up on Universal Passwords, but
reference to reverse encryption seems un-appealing.

Any input is appreciated
