I'm trying to debug automount refusal to mount volumes.  The manual
mount works fine:

> ypcat -k auto.home | grep robert
robert remotehost:/export/users/car073/robert

then

> mount remotehost:/export/users/car073/robert /home/robert

and ls /home/robert works as expected. However, if I

> automount /var/autofs/home/ yp auto.home

and then try to ls /var/autofs/home/robert, I get 

ls:/var/autofs/home/robert: No such file or directory, 

and /var/log/syslog contains

localhost automount[23333]: failed to mount /var/autofs/home/robert

I've also verified that I'm able to automount locally exported
directories (using a "file" map, however).

One point is that the remote host is accessed through a VPN tunnel.

I've attached automount syslog entries using the -d and -v automount
command line options. I suspect "winner=(null)" is a clue but I have
no idea what it means.

Thanks for any help,
Robert
