	inspired by lha@stacken.kth.se

2000-12-16  Johan Danielsson  <joda@pdc.kth.se>

	* lib/krb5/krb5.h: remove des.h, it's not needed and applications
	should not have to make sure to find it.

2000-02-03  Assar Westerlund  <assar@sics.se>

	* lib/krb5/rd_req.c (get_key_from_keytab): rename parameter to
	`out_key' to avoid conflicting with label.  reported by Sean Doran
	<smd@ebone.net>

2000-02-02  Assar Westerlund  <assar@sics.se>

	* lib/krb5/expand_hostname.c: remember to lower-case host names.
	bug reported by <amu@mit.edu>

	* kdc/kerberos4.c (do_version4): look at check_ticket_addresses
	and emulate that by setting krb_ignore_ip_address (not a great
	interface but it doesn't seem like the time to go around fixing
	libkrb stuff now)

2000-02-01  Johan Danielsson  <joda@pdc.kth.se>

	* kuser/kinit.c: change --noaddresses into --no-addresses

2000-01-28  Assar Westerlund  <assar@sics.se>

	forwardable and not proxiable

2000-01-26  Assar Westerlund  <assar@sics.se>

	* lib/krb5/crypto.c: update to pseudo-standard APIs for
	md4,md5,sha.  some changes to libdes calls to make them more
	portable.

2000-01-21  Assar Westerlund  <assar@sics.se>

	* lib/krb5/verify_init.c (krb5_verify_init_creds): make sure to
 	clean up the correct creds.

2000-01-16  Assar Westerlund  <assar@sics.se>

	* lib/krb5/principal.c (append_component): change parameter to
	`const char *'.  check malloc
	* lib/krb5/principal.c (append_component, va_ext_princ, va_princ):
	const-ize
	* lib/krb5/mk_req.c (krb5_mk_req): make `service' and `hostname'
	const
	* lib/krb5/principal.c (replace_chars): also add space here
	* lib/krb5/principal.c: (quotable_chars): add space

2000-01-12  Assar Westerlund  <assar@sics.se>

	* kdc/kerberos4.c (do_version4): check if preauth was required and
	bail-out if so since there's no way that could be done in v4.
	Return NULL_KEY as an error to the client (which is non-obvious,
	but what can you do?)

2000-01-09  Assar Westerlund  <assar@sics.se>

	* lib/krb5/principal.c (krb5_sname_to_principal): use
	krb5_expand_hostname_realms
	* lib/krb5/mk_req.c (krb5_km_req): use krb5_expand_hostname_realms
	* lib/krb5/expand_hostname.c (krb5_expand_hostname_realms): new
	variant of krb5_expand_hostname that tries until it expands into
	something that's digestable by krb5_get_host_realm, returning also
	the result from that function.

2000-01-08  Assar Westerlund  <assar@sics.se>

	* Release 0.2m

2000-01-08  Assar Westerlund  <assar@sics.se>

	* lib/krb5/principal.c (krb5_sname_to_principal): use
	krb5_expand_hostname
	* lib/krb5/expand_hostname.c (krb5_expand_hostname): handle
	ai_canonname being set in any of the addresses returnedby
	getaddrinfo.  glibc apparently returns the reverse lookup of every
	address in ai_canonname.

	* Release 0.2l

2000-01-06  Assar Westerlund  <assar@sics.se>

2000-01-06  Assar Westerlund  <assar@sics.se>

	* lib/krb5/send_to_kdc.c (krb5_sendto_kdc): advance colon so that
	we actually parse the port number.  based on a patch from Leif
	Johansson <leifj@it.su.se>

2000-01-02  Assar Westerlund  <assar@sics.se>
