Hi Bharath,

  Were you able to get a solution to this? I just upgraded to Ubuntu 14.04
(from 11.04) and am experienced this same issue. Your post actually helped
me localize it to the external auth plugin.

  I found that I was running and older version (0.20) of the plugin. When I
upgraded to version 0.25, the issue went away.

Thanks, and hope that helps you.

-Matt
