"uname -a" fails when logging into Solaris 9 host

[Shawn Duffy]

I am trying to execute local security checks on a remote Solaris 9
Sparc box.  My ssh keys are set up properly and Nessus is able to log
in, however, it returns with the error:

It was possible to log into the remote host using the supplied
password, however the execution of the command "uname -a" failed, so
local security checks have not been enabled.

Yet when logging into the box normally it works fine.  This appears to
be a PATH problem and I am wondering if SSHd needs to be configured
with the --with-default-path option.  This, of course, is the default
OpenSSH that ships with Solaris 9.

Any help would be appreciated...
