Grouper Users - Open Discussion List

[Marwan Ali Shaher <>]

For those interested, a small modification to the built-in "GrouperUniqueExtensionHook" achieves the desired behavior. That is, if the desired behavior is to prevent the creation of case-insensitive groups names, even across different stems. Compiling after modifying the following two lines in the hook's source code

     long count = HibernateSession.byHqlStatic().createQuery("select count(g) from Group as g where g.extensionDb = :theExtension")        
         .setString("theExtension", group.getExtension()).uniqueResult(long.class);

with

     long count = HibernateSession.byHqlStatic().createQuery("select count(g) from Group as g where (lower(g.extensionDb) = :theExtension)")
         .setString("theExtension", group.getExtension().toLowerCase()).uniqueResult(long.class);

should do it.

Thanks,

I'm experiencing something different (or maybe that's expected?), when
trying to create groups across different stems with different case
naming. My API's grouper.loader looks like this:
hooks.group.class =
edu.internet2.middleware.grouper.hooks.examples.GroupUniqueNameCaseInsensitiveHook,edu.internet2.middleware.grouper.hooks.examples.GroupUniqueExtensionHook

- First, a group is created:
gsh 1% addGroup("teststem:substem1","testgroup1","testgroup1") ;

- attempting to add a group named "testgroup1" in substem2 is not allowed as expected
gsh 2% addGroup("teststem:substem2","testgroup1","testgroup1");
// Error: unable to evaluate command: Sourced file: inline evaluation of: ``addGroup("teststem:substem2","testgroup1","testgroup1");'' : Error invoking compiled command: : Error in compiled command: edu.internet2.middleware.grouper.hooks.logic.HookVeto: veto.group.unique.extension: The group ID is already in use, please use a different ID

- attempting to add a group named "TESTGROUP1" in substem1 is also not allowed. That is great.
gsh 3% addGroup("teststem:substem1","TESTGROUP1","TESTGROUP1");
// Error: unable to evaluate command: Sourced file: inline evaluation of: ``addGroup("teststem:substem1","TESTGROUP1","TESTGROUP1");'' : Error invoking compiled command: : Error in compiled command: edu.internet2.middleware.grouper.hooks.logic.HookVeto: veto.group.unique.nameCaseInsensitive: The group ID is already in use, please use a different ID

- But, attempting to add a group named "TESTGROUP1" in substem2 is allowed
gsh 4% addGroup("teststem:substem2","TESTGROUP1","TESTGROUP1");
group: name='teststem:substem2:TESTGROUP1' displayName='teststem:substem2:TESTGROUP1' uuid='9fe717125819401bbe808a6e88decb52'

gsh 5% getGroups("substem");
group: name='teststem:substem1:testgroup1' displayName='teststem:substem1:testgroup1' uuid='87da692b7c0d4bfc994367b4e4e3eb6d'
group: name='teststem:substem2:TESTGROUP1' displayName='teststem:substem2:TESTGROUP1' uuid='9fe717125819401bbe808a6e88decb52'

Unless I'm missing something, it would be great if the case
insensitivity worked across stems. Our use case is that we are creating
groups via Grouper in Active Directory. Group names, or object names in
general, are unique there. We can concentrate on developing a custom
hook to check against our subject names and other non-group objects if
the group name uniqueness is handled by the built-in hooks.
