Subject Re: Roles in JNDIRealms

If you are using Tomcat 4.1.3, there are two modes that you can use for
checking roles. If you set roleSearch, it will look for search for group
objects that contain a list of users for each group. If you set
userRoleName, it will get the group information out of the user's entry
instead. i.e. you don't need separate group objects.

If you are using Active Directory, I found that you can use a setup similar
to the following.

This goes in server.xml,

<Realm className="org.apache.catalina.realm.JNDIRealm"
 userBase="cn=Users, dc=mydomain"

Group membership is stored in an attribute named memberOf in Active
Directory. myadminuser doesn't really have to be an admin user in AD. It
just has to have read permission to the memberOf attribute which is visible
to normal user accounts by default.

This goes in web.xml,


In the above example, I created a group in the Users container named Tomcat.
If you want to see how things are organized in Active Directory, you can use
LDIFDE to dump the directory into an LDIF file. That's how I figured it out.
