Summary: NullPointerException in JNDIRealm
Product: Tomcat 6
Version: 6.0.20
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org

Patch to fix NPE
There is a NullPointerException being thrown when the server attempts to look
up a non-existent user in JNDIRealm.
Specifically, the getUser(DirContext, String) method will return null if the
user is not found. However, getPrincipal(DirContext, String) will not check to
see if the result from getUser() is null.
I'm attaching a patch from the 6.0.20 tag but this should also be backported to
the 5.5.x branch as well because the issue exists there.
