libgssglue-0.2

libgssglue-0.2

[Kevin Coffman]

A new version of library libgssglue is now available from:

http://www.citi.umich.edu/projects/nfsv4/linux/libgssglue/libgssglue-0.2.tar.gz

Changes since libgssglue-0.1:

	* Modify the gss_acquire_cred() code to accept, and
	  properly handle, an input name of GSS_C_NO_NAME.
	  Other misc. changes to support this change.
	* Remove some generated files from git.  Change
	  autogen.sh to clean up files that might become
	  outdated and incompatible.

Hi,
So far, I'm stumped.  I've been unable to reproduce this on my Fedora
13 machine.  I have a slightly different version of libc, an earlier
version of kerberos, and a later version of nfs-utils (the pnfs
version).  I went back to stock versions of everything and simply
