[Serusers] Authentication question

[Nimal Ratnayake]

Hi,

I want all users who have accounts on host A to have access to ser which 
runs on
host B, (without having to add them again to the mysql database on host B.)

I learned that Radius Digest Authentication cannot be used because it 
needs the
Radius server to know the cleartext password of the user.  Is there any 
other
method that I can use in this situation?
