Subject: 4.3 /bin/passwd does not deal with /etc/shells properly
Index: /usr/src/bin/passwd.c 4.3BSD
Description:
It is possible to request a shell that is valid as a new shell,
but /bin/passwd will claim it is no good.
Repeat-By:
Run passwd to request a new shell. Ask for a shell that is before
your old shell in the list in /etc/shells.
Fix:
Apply the following patch:
RCS file: RCS/passwd.c,v
retrieving revision 1.1
diff -c -r1.1 passwd.c
