Summary: Nested groups in JNDI realm with non-recursive
implementation
Product: Tomcat 6
Version: unspecified
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: enhancement
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org

Patch which replaced the recursive method with a while loop ("memberOf
Algorithm")
I have modified the method getRoles in org.apache.catalina.realm.JNDIRealm in
the trunk in order to use a while loop to detect nested groups (instead of the
recursive method currently implemented there).
The algorithm is inspired by the article "Practices in Directory Groups" found
here:
http://middleware.internet2.edu/dir/groups/internet2-mace-dir-groups-best-practices-200210.htm
It avoids group slurping and handles cyclic group memberships as well.
Find a patch attached.
Greetings from Amsterdam, Stefan
