[MPICH] Problems launching non-administrative jobs under mpich2 W2k

[Rabih CHAAR]

Hello everyone,
i am trying to launch a mpi job as user alpha with non administrative
rights.

Using mpiexec -register alpha ... followed by 
mpiexec -validate gives
Failure

Changing alpha rights to administrator (no change in registry as to
the
crypted password) followed by
mpiexec -validate gives
SUCCESS


If no user is stored in the registry, trying to launch a mpiexec and
prompting credentials for user alpha on the command line gives the
error

Credentials for \alpha rejected connecting to 127.0.0.1


This seems to come from the file smpd_state_machine.c in the function
smpd_state_reading_process_result (line 5654)


if (strcmp(context->pwd_request, SMPD_AUTHENTICATION_ACCEPTED_STR))
    {
	char *host_ptr;
...
	if (host_ptr) (line 5680)
>>>>	    printf("Credentials for %s rejected connecting to %s\n",
context->account, host_ptr);
	else



Any help or advice is appreciated.

Thanks in advance.
