I’m not 100% certain it is a X problem.
As the syslog lines
Nov 5 17:16:44 linux-ypbf nxexec: PAM unable to dlopen(/lib64/security/pam_pwcheck.so)
Nov 5 17:16:44 linux-ypbf nxexec: PAM [error: /lib64/security/pam_pwcheck.so: undefined symbol: pam_syslog]
Nov 5 17:16:44 linux-ypbf nxexec: PAM adding faulty module: /lib64/security/pam_pwcheck.so
are suggesting it seems to be a pam problem.
And de facto the pam module on my distro seems buggy
ldd -r /lib64/security/pam_pwcheck.so
undefined symbol: pam_syslog (/lib64/security/pam_pwcheck.so)

As a check I’d like to avoid using the PAM module for authentication.
Is this possible with the free version?
I tried this in the config file:
diff /usr/NX/etc/server.cfg /usr/NX/etc/server.cfg.old
242c242
< EnableUserDB 0
—
> #EnableUserDB 0
266c266
< SSHDAuthServer 127.0.0.1
—
> #SSHDAuthServer 127.0.0.1
272c272
< SSHDAuthPort 22
—
> #SSHDAuthPort 22
But it does nothing.
