[Samba] Cannot start Samba 3.0.23a

[Michael Breen]

I just installed Samba 3.0.23a from the sources on a Slackware 10
server kernal version 2.4.26. I didn't get any errors during
installation. When I try to start the Samba daemon by smdb -D nothing
happens. Here is a snippet from log.smbd:

[2006/07/28 20:22:27, 0] smbd/server.c:main(847)
  smbd version 3.0.23a started.
