	characters.

2000-04-26  Ken Raeburn  <raeburn@mit.edu>
	    Nalin Dahyabhai  <nalin@redhat.com>

	* main.c (DEBUG): Don't define.
	(usage): Remove -C option from description.
	(sweep_up): Deleted second argument; all callers changed.
	(main): Support -D option only if DEBUG is defined.  Initialize
	ruid on entry.  Set effective uid to ruid before processing
	argument list.  Removed -C option from -z/-Z conflict messages.
	Report errors trying to stat source ccache using com_err.  Verify
	that getpwuid's returned data for source user has correct uid.

	* ksu.M: Updates for removal of -C option.

2000-01-27  Ken Raeburn  <raeburn@mit.edu>

	realloc, and strdup that print messages and exit if memory
	allocation fails.
	* ksu.h (xmalloc, xrealloc, xcalloc, xstrdup): Declare.
	* Makefile.in (SRCS, OBJS): Use it.
	* authorization.c, ccache.c, heuristic.c, main.c: Change all calls
	to malloc, calloc, realloc, and strdup to call x* versions if the
	return value is not checked before use.

	* authorization.c (auth_cleanup): Ditch int arguments, check for
	null pointers instead.
	(krb5_authorization): Update calls.  Initialize file pointers to
	null.
	(init_auth_names): Check for buffer overflow.
	(fcmd_resolve): Ensure enough buffer space is allocated.
	(find_first_cmd_that_exists): Likewise.  Use strcat instead of
	sprintf'ing a buffer into itself.

	* krb_auth_su.c (dump_principal, plain_dump_principal): Reformat
	slightly.

	* main.c (cc_source_tag, cc_source_tag_tmp): Now point to const.

	line without losing CPP search patchs and defines. Some associated
	Makefile cleanup. [from wsanchez@apple.com]

1999-08-23  Ken Raeburn  <raeburn@mit.edu>

	* heuristic.c (find_ticket): Use flag KRB5_TC_SUPPORTED_KTYPES
	when calling krb5_cc_retrieve_cred.

	* krb_auth_su.c (krb5_get_tkt_via_passwd): Remove call to

Tue Sep 10 14:15:02 1996  Tom Yu  <tlyu@mit.edu>

	* ksu.M: remove ".so man1/header.doc"

Thu Aug  8 12:31:30 1996  Sam Hartman  <hartmans@mit.edu>

Sat May 25 16:11:55 1996  Sam Hartman  <hartmans@mit.edu>

	* configure.in: Use aname db libs.

Tue May 21 19:14:27 1996  Sam Hartman  <hartmans@mit.edu>

	* Makefile.in (install): Ignore error return from installation of
 	ksu; if we can't set the setuid bit (AFS or non-root), we should
 	still continue.

Mon May 20 00:07:16 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* main.c (main):  Do not force source cache open if we are going to use it as the target.

Sun May 19 13:41:21 1996  Sam Hartman  <hartmans@mit.edu>

	* main.c: Force source ccache to stay open between transactions.

Sat May 18 16:39:15 1996  Sam Hartman  <hartmans@tertius.mit.edu>

	* configure.in: Use libkrb5util to get krb5_seteuid

	* heuristic.c (get_best_princ_for_target): Remove seteuid around stat call and insert call to krb5_seteuid before accessing .k5login or .k5users.

	* main.c (main): Insert appropriate calls to krb5_seteuid so that
        files are accessed as appropriate.  Also, remove code to copy
        tickets obtained while running ksu overthe source cache; this is
        not appropriate because it changes the ownership of the source
        cache.

Mon May 13 06:50:12 1996  Richard Basch  <basch@lehman.com>

	* authorization.c: users in the .k5login were not permitted to use
	the '-e command' flag; the man page does not indicate this should fail.
	All users in .k5login, and those in .k5users (for the specified cmd)
	are now allowed to execute commands.
	Also, a lot of indentation cleanup was done.

	* configure.in heuristic.c:
	Before getting the best principal from the ccache, reset the euid;
	we don't want to use someone else's ccache.
	Also, a lot of indentation cleanup was done.

Wed Apr 10 20:24:49 1996  Richard Basch  <basch@lehman.com>

	* main.c, krb_auth_su.c: Mostly cosmetic cleanup of output
	statements.  Also, rather than computing the default host key,
	let the library routine do it.

	* main.c (main): Handle suspend/fg properly.

Fri Mar 29 23:35:53 1996  Chris Provenzano  <proven@cygnus.com>

	* ccache.c main.c: Remove krb5_ccache_refresh(). All this functionality
	is is done in the krb5_ccache_copy(), and the way refresh() was
	implemented it was generating a new ccache owner by root (ksu is suid)
	over the old ccache, thereby making it possible that programs 
	accessing the ccache during this time would fail.

Wed Mar 13 17:45:11 1996  Ken Raeburn  <raeburn@cygnus.com>

	* configure.in: Use AC_HEADER_STDARG.

Wed Nov  8 17:54:11 1995  Theodore Y. Ts'o  <tytso@dcl>

	* ksu.h: Remove local_realm from krb5_authorization.

	* authorization.c (krb5_authorization): Remove old copied code
		that is in krb5 library and is out of date. Use the
		configurable aname to localname methods.

	* main.c (main): Add krb5_secure_config_files so that users cannot
		override system config files.
	

Wed Sep 06 14:20:57 1995   Chris Provenzano (proven@mit.edu)

        * krb_auth_su.c : s/keytype/enctype/g, s/KEYTYPE/ENCTYPE/g

Tue Sep 05 22:10:34 1995   Chris Provenzano (proven@mit.edu)

        * krb_auth_su.c : Remove krb5_enctype references, and replace with

	* configure.in: Don't link with -lkadm.

Tue Jul 11 11:10:13 1995  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* main.c (main): Remove extraneous argument to call to
		krb5_parse_lifetime. Add context argument to call to

	* authorization.c, heuristic.c, krb_auth_su.c: Add prototypes
		for static functions. Add missing arguments to
		_dbm_an_to_ln call.

	* configure.in: Remove standardized set of autoconf macros, which
		are now handled by CONFIG_RULES.

Tue May  9 15:52:15 1995  Ezra Peisach  <epeisach@kangaroo.mit.edu>

	* krb_auth_su.c (krb5_auth_check): Add missing context
