SSH in a captive account?
' System error message: 'captive account - spawn command not allowed'
Is there any workaround to this? Or are SSH commands not going to work from a captive account?

Re: SSH in a captive account?
/SUBPROCESSES (/IDENTIFICATION = xxxxxxxx)
does show a subprocess when SCP is run, and
a quick dump of the executable
(SYS$SYSTEM:TCPIP$SSH_SCP2.EXE) does show
what looks like message text mentioning
"sys$creprc()", so I'd guess that you're
doomed.
A quick Google search for:
scp subprocess
turns up a few places which say things like:
Recall that the command:
$ scp ... S:file ...
actually runs ssh in a subprocess to connect to S and invoke a remote scp server. [...]
(http://www.unix.org.ua/orelly/networking_2ndEd/ssh/ch11_05.htm)
All of which seems to reinforce the initial
impression of doom.

Re: SSH in a captive account?
The big hammer fix would be to set bit 6 in the SYSGEN parameter SECURITY_POLICY - this allows SPAWN from CAPTIVE accounts. Depending on your environment, it might not be appropriate to open this hole.
Note SECURITY_POLICY is NOT dynamic so it's a reboot to set or clear it.
If the SPAWN command is in DCL, you could add /TRUSTED, or if you can get at the source code, add the flag CLI$M_TRUSTED to the LIB$SPAWN FLAGS parameter.
I checked the SCP command for a "TRUSTED" flag, nothing obvious.
