Subject: * get_in_tkt.c (krb5_get_in_tkt): Remove the etype_info argument from
X-Git-Tag: krb5-1.0-beta6~831
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=5a341becfda1deaf4dd590b70939c0c622597d1e;p=krb5.git

* get_in_tkt.c (krb5_get_in_tkt): Remove the etype_info argument from
	the call to krb5_obtain_padata.

* preauth.c (krb5_obtain_padata): Use the PADATA_ETYPE_INFO preauth,
	if it exists, to determine which salt type to use when encrypting the
	preauthentication data.  Remove the etype_info argument.
