The RBAC structure that I speak of is contained within our application. 
Being able to have IPA clients request the XML blob of role mappings to
internal application commanding authorizations is what I was looking
for.

Is it possible to create IPA Roles that mean nothing to IPA yet our
independent application could query and use them with it's internal
security mechanisms? 

Could extending the dirsrv schema to include attributes to be accessed
for the security of the independent application be created to work in
conjunction with these custom defined roles?
 
Having the IPA Server available to all hosts that run the application is
what we desire. We use *_attr Name Service Switch maps to access these
roles and attributes from our Solaris implementation. 

Unless I am mistaken, HBAC might give us options as to whom may run our
applications on particular hosts, but it would not help in defining who
could run the internal application directives that we seek to map to
users roles.
Sudo doesn't help for the internal commanding our application desires to
control.

Thanks for any ideas you can lend.

Regards,
Rodney.
