Ticket 524

Created attachment 514 [details]
AuthInfo:  Adds the ability to specify an alternate MUNGE socket.

It turns out, the sys admins really need on BG/Q the MungeSocket functionality that Phil added to our v2.3.3 here:
https://github.com/chaos/slurm/commit/7d31af59f89b689408d12d607c6e5c4e31a8f2d8

The attached patch is a port of the above to the latest 13.12 development branch.  It follows Danny's request to use AuthInfo instead of MungeSocket for consistency sake.

I tested the patch and it works on a simulated machine.  I have not had the chance to port this to v2.6 and run it on a real machine.

The attached patch includes all of Phil's original patch (substituting AuthInfo) plus some additional changes I though would be required.  I used the existing code supporting authtype to locate possible additions for authinfo.

There were some files I opted not to change.  For example, I did not create an auth_info analog to slurm_get_auth_type() and slurm_set_auth_type().  I also judged that the auth_type code in src/slurmctld/read_config.c did not have to be expanded to include auth_info.

If you feel these sections need to include auth_info, let me know and I'll make the patch match up with auth_type exactly.

Again, it seemed to work on my test system.  And Phil's original MungeSocket patch has been working fine on our v2.3.3 systems.
