Hi,

Hope this helps:

I would say change this in the config file of ssh daemon
UsePrivilegeSeparation no


Cheers,
Cristian



Sadly, I'm running into other problems when I disable priv sep.  If I
start the daemon manually as follows, this is what I get:


From remote host


# ssh -l dallas 172.16.1.34

On the target I see these errors:

debug1: userauth-request for user dallas service ssh-connection method
none
debug1: attempt 0 failures 0
Invalid user dallas from 172.16.1.33
input_userauth_request: invalid user dallas
Failed none for invalid user dallas from 172.16.1.33 port 58128 ssh2

Can OpenSSH function without PAM if I also disable priv sep?

Currently I do not have PAM enabled in my OpenSSH build.

Thanks,
Dallas

p.s. I noticed in a document found on the web the following quote:

"PAM-enabled OpenSSH is known to function with privsep on Linux."
