When using "migcred" for such utils like migfiles etc where does CASA stores
my admincredentials?

I enter "migcred -i servername -l" and migfiles does work as expected until
it suddenly stops working
and ask for admin account and password.

I got like 80 servers and a script running for backing up all files but
suddenly all servers requires
the admin account again... so the replication process stops.

Please advice :)
