jdolecek 03cdaf03c9 Add some examples of usage. Modelled after what is in Solaris manpage, 
though no text has been actually copied from there (for legal reasons).

abs ddcdaa6b45 Set SU_FROM environment variable. This can be used to determine a 'su -' 
shell from a real login shell (but only if you care).

mjl 8cb2edab13 Removed code that would squash root's path when suing to root, 
restores old behaviour of su.

drochner 85cbf55d16 Since our gcc doesn't warn about NULL format strings anymore, we can 
fix the incorrect err(1, "%s", "") et al.
Closes PR bin/7592 by cgd.

mjl d6634fdb48 Mention "-" is the same as "-l". Closes PR/8499 by Matthew Aldous. 1999-09-27 19:41:33 +00:00
christos 36dc48ce6e Amazing how this worked for so long. setenv(3) expects environ(7) to be 
a malloc'ed pointer and it tries to realloc(3) it if it had to grow it
before. su(1) gave it a pointer from the stack which caused realloc to
core dump.

abs 3191b7662f Looks like some recent changes broke the 'anyone can su if wheel is not present 
or empty' rule. Fix.

christos b0a604e893 Remove Solaris shadow password support... Better to do this in the 
compatibility library. Suggested by Matt.
 1999-03-15 09:30:51 +00:00
christos 024eb1b8d7 - Add support for Solaris style shadow password files 
- Enable su - option if BSD4_4 is not defined
- Add compile time option ROOTAUTH (not enabled), where people belonging
  to the ROOTAUTH group can su to root by supplying their own password.

scottr 96df5ccdbf Don't warn about being in a user's ACL if Kerberos appears to be 
unconfigured.  We determine this the same way that passwd(1) does.
 1999-02-20 00:20:59 +00:00
scottr 8481f548e2 Remove the crypto-related bits until such time as we have a fully- 
integrated source tree.  Export-controlled versions of these are now
built during the domestic build process.

- be safe will buffers that hold hostnames

mycroft 4163fb775c Make this compile without SKEY. 1997-10-12 12:54:20 +00:00
lukem aaa55367ba 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
lukem 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

ghudson b440233d15 Document the recent change in group wheel semantics. Also, it wasn't 
previously documented that anyone could su to root if group 0 didn't
exist.
 1997-01-31 23:12:17 +00:00
ghudson 1b6b85b894 As discussed on tech-userlevel, allow anyone to su if group wheel has 
no members (if you have just "root" as a member, which is the shipped
default, then no one can su, as before).

- RCSid police.

christos 17b3a275d4 Fix PR/2837: su [login [args]] had the wrong usage and did not work properly. Build the correct argument list and add -c for the shells. 
Fix PR/2839: su will not build with Kerberos.

- Also:
	-Don't coredump when $TERM is not set.
	-Add prototypes, remove local old style declarations of system
	 functions.
	-Recognize shells that contain "csh" as being csh alike.
	-Don't build with SKEY unconditionally. Obey bsd.own.mk.
