[ome-users] Issues with NewUserGroupBean implementation

[Harri Jäälinoja]

Hi,

attached is my first attempt at implementing NewUserGroupBean to get 
group info from our LDAP.When I try to login, it prints this in the 
Blitz log file:

2012-03-23 17:36:37,490 DEBUG [             hyldap.HyHcNewUserGroupBean] 
(l.Server-1) grpName matched 
uid=grp-A91900-bi-vart,ou=alma_workgroups,ou=groups,o=hy
2012-03-23 17:36:37,490 DEBUG [             hyldap.HyHcNewUserGroupBean] 
(l.Server-1) grpName matched BI-Vartiainen

So it seems the code should next call
provider.createGroup(grpOmeName, null, false)
to create a new group "BI-Vartiainen".


However, login fails, and I find this in the log:

2012-03-23 17:36:37,641 WARN  [ome.services.sessions.SessionManagerImpl] 
(l.Server-5) Exception while running executeDefaultGroup
ome.conditions.ValidationException: The user 2 has no default group set.

(l.Server-5)  Excp:    ome.conditions.ApiUsageException: Can't find 
default group for hajaalin


At an earlier attempt (difference between this was only amount of 
logging) I got also this error:

2012-03-23 17:24:47,249 INFO  [                      ome.logic.LdapImpl]

...

Since it behaved differently on the second time, it might be interesting 
to see if I can reproduce the first error by removing the user I was 
logging in as. But how can I remove a user? In webadmin I saw only a 
button to inactivate a user.

I have set like this:
[omero at lmu-omero2 OMERO.server-Beta-4.3.3]$ omero config set 
omero.ldap.sync_on_login true
This sounds like it should make the same checks every time, so that the 
first login would not be special in any way.

I am new to git, but from the example that Josh sent me earlier I got 
the impression that somewhere in the OMERO source code system is now 
also a little pocket reserved for this "hyldap" component. If this is 
so, would it make sense that I upload my code there, instead of sending 
it attached in email? But how do I do that?

Regards,
Harri
