Hi,
JR core 2.0.0
In UserAccessControlProvider.compilePermissions(...), if no principal relating 
to a user node can be found, then a set or read only compiled permissions is 
provided. That set gives the session read only access to the entire security 
workspace regardless of path.

If the user node is found, then an instance of 
UserAccessControlProvider.CompilePermissions is used and in 
UserAccessControlProvider.CompilePermissions.buildResult(...) there is a check 
for no user node. If there is no user node, all permissions are denied 
regardless of path.

Although the first case will never happen for an installation of Jackrabbit 
where there are no custom PrincipalManagers, I suspect, based on the impl of 
UserAccessControlProvider.CompilePermissions.buildResult(...) was to deny all 
access to the security workspace where there was no corresponding user node in 
a set of principals.

Did I read the code right ?
Is this a bug in 2.0.0 ?
Has it already been fixed in a later release ?

Ian
