[mpich-discuss] Credentials rejected

[Chris George]

Hi Jayesh,

Thanks for the prompt reply.  In fact I have now solved the problem.   
I did not realise the password had to be the logon password for the  
user: normally one is only asked to repeat a password when inventing  
one.  I was using an account with no password, so I invented one for  
MPI.  I have now created a password for the user and registered it and  
all is well.

Regards,
Chris
