[Condor-users] v6.6.8, Windows XP, universes and condor_store_cred.

[Patrick Townsend <patrick.townsend@xxxxxxxxxxxxx>]

Hi

I'm confused about the usefulness of condor_store_cred. Can anyone help me 
understand this please?

We've been using v6.4.7 without DAGman or Condor-g for ~2 years on Windows 
XP clients + server and recently moved the server to Windows Server 2003. 
We have around 250 running nodes and usually 10-15 users submitting from 
their own desktops. Typically there are up to 5,000 jobs in the queue, but 
several times a year there are 50,000. We are well used to jobs running as 
the local user condor_reuse_vm1 and having to squirt data around using file 
transfer. A migration to v6.6.8 is imminent - the bugfix list looks very 
attractive!

v6.6.8 manual section 6.2.1 states "The ability to run the job with the 
same credentials as the submitting user is not yet supported. Instead, 
Condor will use a set of accounts (one per VM) with minimal access rights 
to run the job." Fine, as per v6.4.7.

In the v6.6.8 manual command reference section condor_store_cred is 
described as "condor store cred stores the password of a user/domain pair 
securely in the Windows registry. Using this stored password, Condor is 
able to run jobs with the user ID of the submitting user when running 
scheduler universe jobs and DAGMan."

When might the scheduler universe be used in Windows?

If I'm using just the vanilla universe without DAGman, condor_store_cred 
doesn't appear to offer anything. Can I turn it off?

Should I consider using DAGman?

	regards
