Debugging NSS_WRAPPER in the samba test environment.

[Jeremy Allison]

I'm trying to debug a test case I'm writing,
and I'd really like to see the debug test
messages from NSS_WRAPPER.

So I tried adding 

$ENV{NSS_WRAPPER_DEBUGLEVEL} = 10;

to the startup scripts for smbd and winbindd in
selftest/target/Samba3.pm, but don't see any
NWRAP_XXX messages in any logs, or in the
stdout.

Anyone know how to get lib/nss_wrapper/nss_wrapper.c
debug to work ?

Cheers,

	Jeremy.
