Subject: sn2princ.c (krb5_sname_to_principal): Windows NT5's broken resolver
X-Git-Tag: krb5-1.1-beta1~420
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ee3a7528633657e0421b37b26a7fbd9ee3705293;p=krb5.git

sn2princ.c (krb5_sname_to_principal): Windows NT5's broken resolver
	gratuitously tacks on a trailing period to the hostname (at least it
	does in Beta2).  Deal with this brain-damage.
