Unable to get windows domain authentication working (-delegate) with a network executable.

The commands below demonstrate the problem I am seeing. The -delegate option works for a local executable, but not one on a network drive.

 

# Register to use password authentication
C:\Users\local>mpiexec -register
account (domain\user) [COMPANY\local]:
password:
confirm password:
Password encrypted into the Registry.

# Demonstrate with local executable
C:\Users\local>mpiexec -ppn 1 -hosts local-computer,cluster-01 hostname.exe
cluster-01
local-computer

# Demonstrate mpi use with network drive (hostname.exe is copied from c:\windows\system32)
C:\Users\local>mpiexec -ppn 1 -hosts local-computer,cluster-01 \\network\hostname.exe
local-computer
cluster-01

# Unregister password authentication
C:\Users\local>mpiexec -unregister
Account and password removed from the Registry.

# Fails as expected
C:\Users\local>mpiexec -ppn 1 -hosts local-computer,cluster-01 hostname.exe
User credentials needed to launch processes: ^C

# Domain-based authentication works
C:\Users\local>mpiexec -delegate -ppn 1 -hosts local-computer,cluster-01 hostname.exe
cluster-01
local-computer

# But not from a network drive
C:\Users\local>mpiexec -delegate -ppn 1 -hosts local-computer,cluster-01 \\network\hostname.exe
local-computer
[-1:9156]ERROR:execvp error on file: \\network\hostname.exe, Access is denied.

Hi Jeffrey,


Could you tell us on which node you are running, you can get that by running whoami command.

Also are local-computer,cluster-01 part of the network drive(\\network\)? or the \\network is a third system?

Hi Prasanth,

I'm running from local-computer. \\network is a filer UNC path on the same network as the other two computers. There are no firewalls.

Hi Jeffrey,


If all systems belong to the same domain and still -delegate is not working, this seems to be an issue from our side.

We are transferring this to Internal team.
