Subject: If -o sec= is not specified for mount, allow either AUTH_SYS or AUTH_NONE.
X-Git-Tag: nfs-utils-1-1-0-rc1~84
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=afc841a1f2a62645ec2dfaa333baf07e44a03c08;p=nfs-utils.git

If -o sec= is not specified for mount, allow either AUTH_SYS or AUTH_NONE.

Solaris servers, when asked to share a filesystem with an anon-uid, will
report the only available authentication style as AUTH_NONE in the
reply from mountd (even though they actually accept AUTH_SYS and simply
ignore the credentiuals).
So if no sec= is specified we should really accept anything that can easily
be handled.  ie. AUTH_SYS or AUTH_NONE.
