Chris,

We are not running load balanced. Just one server. But the example in your reply was not exactly what I did.

I first saved 2 differently named groups. Then I modified the second group to have the same name as the first group using --saveMode=UPDATE and --groupLookupUuid to find the group to modify. That results in the two groups having the same name and the query behavior I described.

Thanks.

I tried this and couldn’t reproduce. (see output below).

 

Are you on the latest 1.4 branch that has caching enabled, and are you running a load balanced array of web service servers?  I wonder if it is possible that server1 queries for the group, gets a negative that it exists, caches that, then server2 adds the group, then server1 queries to see if the group is there, returns a negative from cache, then adds the group again.

 

Grouper 1.5 has a unique index on group name, so this wont be possible, fyi.  Its not possible for grouper 1.4 to do this.

 

Anyways, I made a tweak to the latest 1.4 so that when adding a group, the query that sees if the group exists is not cached.  If you think this might be the issue, you might want to get latest the latest API, put it in your WS, and try again.

 

If that isn’t the problem, then we probably need to keep looking, let me know.

Subject: [grouper-users] Groups with duplicate names

 

I have found that using GrouperClient I can create 2 groups with the exact same name, and then when I do a findGroupsWs query in GrouperClient, I only get one of the groups returned. It seems like I should not be able to create 2 groups with the exact same name, or I should get both groups back when I query.

 

Details:

Create group 1 with name “ENT:pagTestDup1” using groupSaveWs --saveMode=INSERT

Create group 2 with name “ENT:pagTestDup2” using groupSaveWs --saveMode=INSERT

 

Modify the name of group 2  to be the same as group 1 with this command:

groupSaveWs --name=ENTE:pagTestDup1  --saveMode=UPDATE --groupLookupUuid=13014a29-68f1-27fd-bf17-86af6af4af4d

 

Then, when I do a query:

findGroupsWs --queryFilterType=FIND_BY_GROUP_NAME_APPROXIMATE --groupName=ENT:pagTestD, I only get group 1 returned in the result. However, if I query by each group’s uuid, I see each group is there with the exact same name.

 

This scenario came about because I was trying to determine whether I should ever expect to get more than 1 group returned when I do a findGroups query with –queryFilterType=FIND_BY_GROUP_NAME_EXACT.
