	instead of int and that acts as an in-out parameter (indicating the
	maximum length of the sockaddr to be written)

	* kdc/kerberos4.c:
	make the kvno's in the krb4 universe by the real one % 256, since they
	cannot only be 8 bit, and the v5 ones are actually 32 bits

2002-02-15  Johan Danielsson  <joda@pdc.kth.se>

	* lib/krb5/keytab_keyfile.c (akf_add_entry): don't create the file
	before we need to write to it
	(from Åke Sandgren)

2002-02-14  Johan Danielsson  <joda@pdc.kth.se>

	* configure.in: rk_RETSIGTYPE and rk_BROKEN_REALLOC are called via
	rk_ROKEN (from Gombas Gabor); find inttypes by CHECK_TYPES
	directly

	* lib/krb5/rd_safe.c: actually use the correct key (from Daniel
	Kouril)

2002-02-12  Johan Danielsson  <joda@pdc.kth.se>

	* lib/krb5/context.c (krb5_get_err_text): protect against NULL
	context

2002-02-11  Johan Danielsson  <joda@pdc.kth.se>

	* admin/ktutil.c: no need to use the "modify" keytab anymore

	* lib/krb5/keytab_any.c: implement add and remove

	* lib/krb5/keytab_krb4.c: implement add and remove

	* lib/krb5/store_emem.c (emem_free): clear memory before freeing
	(this should perhaps be selectable with a flag)

2002-02-04  Johan Danielsson  <joda@pdc.kth.se>

	* kdc/config.c (get_dbinfo): if there are database specifications
	in the config file, don't automatically try to use the default
	values (from Gombas Gabor)

	* lib/krb5/log.c (krb5_closelog): don't pass pointer to pointer
	(from Gombas Gabor)

2002-01-30  Johan Danielsson  <joda@pdc.kth.se>

	* admin/list.c: get the default keytab from krb5.conf, and list
	all parts of an ANY type keytab

	* lib/krb5/context.c: default default_keytab_modify to NULL

	* lib/krb5/keytab.c (krb5_kt_default_modify_name): if no modify
	name is specified take it from the first component of the default
	keytab name

2002-01-29  Johan Danielsson  <joda@pdc.kth.se>

	* lib/krb5/keytab.c: compare keytab types case insensitively

2002-01-07  Assar Westerlund  <assar@sics.se>

	* lib/krb5/crypto.c (create_checksum): make usage `unsigned' (it's
	not really a krb5_key_usage).  From Ben Harris <bjh21@netbsd.org>
	* lib/krb5/get_in_tkt.c: use krb5_enctype consistently.  From Ben
	Harris <bjh21@netbsd.org>
	* lib/krb5/crypto.c: use krb5_enctype consistently.  From Ben
	Harris <bjh21@netbsd.org>
	* kdc/kerberos5.c: use krb5_enctype consistently.  From Ben Harris
