samba - Mar 2010 - smbd crashes on Debian Lenny if using Debian's

Hi there,

Installed the latest stable Samba (3.5.1) from the source tarball on a
fresh, minimal Debian Lenny server.  It took me three days to figure
out why the Samba daemon wouldn't run.  The crux of it is this:

=====================================================================
Although I built Samba from source and it has its own version of
libwbclient, it decided to use the Debian-supplied version.  This
doesn't work with smbd for reasons that I haven't investigated.

As soon as I removed the offending libwbclient and set up the library
search path for the Samba-supplied libraries:

prompt # > echo "/usr/local/samba/lib"
>>/etc/ld.so.conf.d/samba.conf
prompt # > ldconfig

the daemon started up fine.

Hoping that this might help anyone else in the same boat.

Shouldn't Samba simply use its own version by default?

Please also replace libwbclient with the compiled version.
