>Description:
I have trouble with using 2.1.x binaries on 2.2-ALPHA.
They are linked with libc.so.2.2 and they can not get a passwd entry for
NIS users.
Like the followings,
(User simokawa is not in local passwd file but in NIS map.)
% csh
% echo ~simokawa
/home/sat/simokawa
% zsh
% echo ~simokawa
zsh: user not found: simokawa
% ldd /usr/local/bin/zsh
/usr/local/bin/zsh:
-ltermcap.2 => /usr/lib/libtermcap.so.2.1 (0x8065000)
-lc.2 => /usr/lib/libc.so.2.2 (0x8069000)
If I rebuild pwd.db by old pwd_mkdb or relink zsh with libc.so.3.0,
it works fine.
I think this is very bad and many pepole upgrading to 2.2 will
encounter same problem. It takes me more than 2 weeks to find out the
reason :-(.
I guess this is because of the following change on mk_pwd.c

NIS cleanups and fixes, the next generation, continued.
pwd_mkdb.c:
- Don't save the PLUSCNT and MINUSCNT tokens: we don't need them anymore.
- Count the + and - entires for NIS together instead of counting + and -
entries seperately. Index all special NIS entries using new _PW_KEYYPBYNUM
token.
pwd.h:
- Remove the PLUSBYNUM, MINUSBYNUM, PLUSCNT and MINUSCNT tokens and replace
then with a single _PW_KEYYPBYNUM token.
----
>How-To-Repeat:
See above.
>Fix:
pwd_mkdb.c should have compatibility with old libc.
Changing pwd_mkdb.c, so that it adds PLUSBYNUM, MINUSBYNUM,
PLUSCNT and MINUSCNT tokens to pwd.db, should solve this problem,
but I'm not sure.
