2011-01-11Allow su -l to login to a user that has a non-existent home directory,Robert Nagy
unless requirehome is specified in login.conf for the login class. If requirehome is not specified the user will be logged in with HOME=/ This is what login(1) and ssh(1) does too. ok millert@
2010-12-13Call setusercontext() with the LOGIN_SETENV flag for "su -l" to pick upTodd C. Miller
environment variables specified in login.conf. Based on a diff from robert@. OK robert@ otto@

2009-10-28rcsid[] and sccsid[] and copyright[] are essentially unmaintained (andTheo de Raadt
unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms

2002-12-17Only call setlogin() if this proccess is a session leader.Todd C. Miller
In practice, this means the login name will be set only if we are exec'd by a shell. This is important because otherwise the parent shell's login name would change too.
2002-12-08GNU semantics say that if optstring begins with '-' thenTodd C. Miller
each non-option shall be treated as arguments to option '\1'. BSD getopt match '-' in optstring with a '-' on the command line. This is used to support deprecated options like "su -" that would otherwise prevent the use of getopt(). Resolving this simply requires that the leading '-' be moved somewhere else (I moved it to the end of optstring) since position within optstring is not meaningful.

2002-11-08In login emulation mode use the same setusercontext() flags asTodd C. Miller
login(1). Previously, setlogin() was not being done in -L mode.
2002-10-16Add a new flag, -L, to cause su(1) to loop asking for a login/passwordTodd C. Miller
repeatedly until the user authenticates or interrupts things. This will be used to make login(1) no longer setuid.
2002-07-22auth_close() was not actually getting called in auth_errx?() (notTodd C. Miller
that it really makes much of a difference). Call vwarnx?() instead of verrx?() and then do the exit inline after auth_close(). That's what I get for doing a cut & paste from err.c...

2001-06-25Instead of trying to do clever and figure out a root instance for Kerberos,Hans Insulander
send tell the auth program who the invoking user is, and rely on it to handle root instances for Kerberos. This makes the code much cleaner and simpler. ok millertt@
2001-06-25Add a "login" option to allow differentiation between authenticationTodd C. Miller
that creates a login session vs. a simple identity check. Gets passed as a -v option to the login scripts. To be used by kerberos to know when to create new tickets.

Closes PR 1246
2000-08-20Add calls to setusercontext() and login_get*(). We basically callTodd C. Miller
setusercontext() in most places where previously we did a setlogin(). Add default login.conf file and put root in the "daemon" login class.
2000-06-30warnx?/errx? paranoia (use "%s" not a bare string unless it is aTodd C. Miller
constant). These are not security holes but it is worth fixing them anyway both for robustness and so folks looking for examples in the tree are not misled into doing something potentially dangerous. Furthermore, it is a bad idea to assume that pathnames will not include '%' in them and that error routines don't return strings with '%' in them (especially in light of the possibility of locales).
