The following reply was made to PR bin/146186; it has been noted by GNATS. From: dfilter@FreeBSD.ORG (dfilter service) To: bug-followup@FreeBSD.org Cc: Subject: Re: bin/146186: commit references a PR Date: Mon, 3 May 2010 07:32:43 +0000 (UTC) Author: mm Date: Mon May 3 07:32:24 2010 New Revision: 207553 URL: http://svn.freebsd.org/changeset/base/207553 Log: Implement the no_user_check option to pam_krb5. This option is available in the Linux implementation of pam_krb5 and allows to authorize a user not known to the local system. Ccache is not used as we don't have a secure uid/gid for the cache file. Usable for authentication of external kerberos users (e.g Active Directory) via PAM from applications like Cyrus saslauthd, PHP or perl.
