Combining several Realms together

[delbd <de...@oma.be>]

Hello everyone,

Can somebody enlight me on the faisability of this in tomcat configuration

- Have user list and user password checked against a JNDI Realm (this is a nis 
mapped jndi realm)
- Have user roles checked against another Realm (eg: database realm)

Why this strange thing?

We have a list of user/password/group exported as NIS yellow pages. We want to 
use this list as this is the passwords users are using to check their email 
and so we know each user already has a password.

However, our J2EE application uses a lot of roles, but access to unix groups 
we have is readonly. If i want to add a user to a role , or create a new 
role, i have to go thru a lengthly process of asking one of the unix admin to 
create them and as those group are used a lot thru several server, he has to 
chekc the implcation of adding such groups. This is quite cumbersome when one 
day we need to create 7 roles and put about 15 users in each. 

Anyway, creating lots of new groups on our unix server is not a possiblity so 
me need to store them somewhere else while still getting user list / password 
from unix/nis.


Any suggestion?
