Ok and it the scp is run on the WN?

I have done some tests, logged on the CEhost as user dteam001 and checked that 
indeed there is always a source file
~dteam001/.lcgjm/globus-cache-export.xxxxxx/globus-cache-export.xxxxxx.gpg

I cannot see (with last) that user dteam001 is logged on WNhost when doing this 
operation. The dest file does not have an absloute path, where is it supposed 
to be put ~dteam001, /var/spool/pbs/somewhere?

There might be a problem with directory access. On the WN, /home uses 
automount:
# service autofs status
Configured Mount Points:
------------------------
/usr/sbin/automount --timeout=60 /home file /etc/auto.home

and in /etc/auto.home there are entries like

dteamsgm        grid.local:/export/home/dteamsgm
dteam001        grid.local:/export/home/dteam001

The same on the CEhost

In addition in /etc/exportfs /export is exported
/export 10.0.0.0/255.0.0.0(rw)

In /var/spool/pbs/mom_priv/config there is currently

$usecp *:/home /home

Should there be /export instead?

In /var/log/message and at the corresponding time of the scp failure there is

sshd[6181]: Accepted hostbased for dteam001 from 10.255.255.254 port 44841 ssh2
sshd(pam_unix)[6183]: session opened for user dteam001 by (uid=18118)
sshd(pam_unix)[6183]: session closed for user dteam001

Cheers,
