can someone please tell me if a dot in a user's name
is valid? Is e.g. "Bruce.Willes" a valid user name?

User objects are stored in eDirectory, home directory
is on nss. Servers are OES and OES2.

How do I escape the dot for the /sbin/rights?
It seems to accept ".cn=Bruce.Willes\.o=test.t=willow"
but is that really correct?

Thanks a lot,
