Re: [Xen-API] Xen API login error

[Stefan Berger <stefanb@xxxxxxxxxx>]

Do you happen to have python PAM installed
on your system? I am asking because I installed version 0.5.0 of PyPAM
and enabled Xen-API authentication by changing xend's config file. Xend
crashes when I use my username and login as credentials. This is on Fedora
Core 7.

If I add the line log.info("A")
to the above, commands work. Very strange. I am not sure where the error
may be coming from but my suspicion is the PyPAM module. I'd disable authentication
in the xend config file and see whether things work better then.
