Re: [condor-users] Using Condor from a web application

[Ian Alderman <alderman@xxxxxxxxxxx>]

Raymond,

There's probably some restriction on the ability of the server to 
either run external binaries or to run external binaries as another 
user.  I'm not familiar at all with Win 2k server, so I'm just 
guessing.  What happens if your VB script does something much simpler, 
such as creating a file in a publicly writable directory such as 
c:\temp or whatever?  If this is successful, who owns the file?

Is it a requirement of your application that the condor jobs run with 
the same credentials as the users themselves?  I've recently heard talk 
of a web application that feeds condor jobs which uses a single account 
created just for this purpose for all jobs it submits.  Unless the 
application requires access to resources available only to the user, 
perhaps this would suit.

Finally, perhaps it would be possible to work around the problem by 
having the web application deposit task information somewhere, and a 
service which did not run in the security context of the web 
application which could retrieve this information and execute the VB 
script.
