There is definitely something strange going on here, if I flush
the winbind cache, then ask for a users info with getent, I get this:

time getent passwd rowland
rowland:*:10000:10000:Rowland Penny:/home/rowland:/bin/bash

real	0m0.054s
user	0m0.004s
sys	0m0.000s

then if I ask for it again:

real	0m0.001s
user	0m0.000s
sys	0m0.000s

is PAM set up correctly ?
