Heimdal gets tokens correctly, access to private directories works. I'm running the arla test suite now; I'm up to hardlink3 with no problems.

I'm going to move on to trying everything on 7.x. I know there are autoconf/etc. things that need to be fixed. Do you want me to work on that or are you likely to have it done already. =20 I do have a tweaked version of your patch---as I recall it contains just one typo fix---at http://setfilepointer.com/pub/arla/20080218-arla.diff There's also the snapshot of the sources I used: http://setfilepointer.com/pub/arla/arla-20080118.tar.bz2 Assuming I get things working on 7.x, I'll update the port I built later today. :) --=20 Alec Kloss alec@SetFilePointer.com IM: angryspamhater@yahoo.com PGP key at http://pgp.mit.edu:11371/pks/lookup?op=3Dget&search=3D0xA241980E "No Bunny!" -- Simon, from Frisky Dingo --lHGcFxmlz1yfXmOs Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFHv/4N2s33paJBmA4RAi6LAJ9YEJqJTVrsniYHJSXqobrc74FNmgCfeMEK Z70j7rSLRbPpLavjfbKV4KA= =RDi8 -----END PGP SIGNATURE----- --lHGcFxmlz1yfXmOs--
