2001-01-11 00:54:57 +00:00
91d1372fc6
If SU_INDIRECT_GROUP is defined (it is by default), then su will
...
consider that SUGROUP and ROOTAUTH group contain the names of
users and groups. If user is not found in the list check_ingroup()
recurses on each member until either user is found or end of chain
is reached.
The above allows su's use of the wheel group to be extended to a large
number of users without necessarily putting them in group wheel, and
in a way that will work over NIS that simply extending the line length
limit in getgrent.c cannot.

As per discussion with mrg, back out parts of previous change.
...
The appropriate entry in /etc/group as returned by getgrnam() is
used to determine if 'su root' may be permitted, rather than
checking if membership exists in the result of getgroups().
The following changes were made regarding the behaviour of the special
group for 'su root'
* allow for definition of SUGROUP (defaults to "wheel") to override group name.
* use getgrnam(SUGROUP) instead of getgrgid(0).
* only scan getgrnam(SUGROUP)->gr_mem when checking for group membership.
* be more specific as to why 'su root' failed
NOTE: If a user's primary group is SUGROUP, and they're not a member
of SUGROUP in /etc/group, they will not be able to su.
1997-07-02 05:42:11 +00:00
8d846dbbd1
* Notify of impending password or account expiry (check against
...
_PASSWORD_WARNDAYS from <pwd.h>). For non-root users, enforce expiry when
it happens. From Simon Gerraty <sjg@zen.void.oz.au> in [bin/935].
* Check for group 0 in process's current group membership (as returned by
getgroups(2)), instead of just looking at the entry for wheel in /etc/group.
Based on code by Dan Caresone <dan@oink.geek.com.au> in [bin/792], and
also solves [bin/2466].
* Clean up to pass -Wall
