I've looked at the transformation pages already.

My question is

If you have two tables: People and Roles. There's a one to many relationship ie. a person can have many roles.

Is there a transformation that can return distinct People with a multivalued attribute that contains each Role? I think the answer is no but I'm not 100% certain and I don't want to advise the wrong thing.

The following occurs if a field is populated twice by transformations:

It is proposed to give a better error message, and upon start-up of Identity Broker, for this error.

Please allow right click, copy in the context menu on the log viewer. Currently without the split screen there is a lot of copying. Further, when providing feedback to the Product Team it is essential to copy the full error message.

Control C works but thats because I'm a keyboard junkie. A lot of young people would prefer a menu option.

When an empty or null string field is used as part of a generated DN for an adapter, they cause a ArgumentOutOfRangeException from the DNGenerators.

Suggestion is to supply a default value for this situation, or supply a better error message (or both).

When attempting a confirming delta import delta sync after a successful export, the following exception is thrown in the new Aurion demo environment (FIM, using Windows 2k8). This is thrown as a stopped-extension-dll-exception in FIM. According to Patrick, this error has not been seen before in other environments. It has been remedied by performing a confirming full import full sync instead.

The extensible extension returned an unsupported error.

Hi Product team,

Import changes are not being processed to adapters when the adapter is disabled.
Should this be processing regardless of if the adapter is enabled/disabled?

Happy to provide screenshots and logs if required

Hi Gents,

Interesting one - we're consistently seeing the below error while running delta imports from IDB into FIM, on the LDAP Groups partition.

Note this is the same error noted in UNINWCSTL-1, however this is not a DN issue.

Nothing is noted in the IDB logs around this, although I have attached a Diagnostic log taken while this occurred.

In investigating, i noted that initially the delta's seemed to be working fine, and then started failing from a specific point - notably 2nd Oct, 2:05 am.

I looked at the IDB ChangeLog table for changes on this adapter around this time, abd found some interesting entries:

ChangeLogKey, AdapterId, ChangeType, ChangeTimestamp, TargetDistinguishedName, NewDistinguishedName, Changes

I sampled around either side, but if you note the 2 entries in the middle are both just before the delta's started failing, and are adding a value to a multivalue field. This seems consistent with the error text aswell.

I've attached full config aswell, let me know if more is provided.

When doing a full import on a placeholder connector with no entities, the following error is returned. This should probably be captured, reported and not classed as an error (its not actually broken, its just a fact of data).
