Tom asks:

the actual question was: I'm trying to obtain a list of all users.

I guess this method should do the trick:

 Collection<Identity> identities = identitySession
 .getPersistenceManager()
 .findIdentity((IdentitySearchControl[])null);

I assume this gets me the users *and* groups, right ?

I only found following search controls:

 if (control instanceof PageSearchControl)
 {
 pageSearchControl = (PageSearchControl)control;
 }
 else if (control instanceof SortByNameSearchControl)
 {
 sortSearchControl = (SortByNameSearchControl)control;
 }
 else if (control instanceof AttributeFilterSearchControl)
 {
 attributeFilterControl = (AttributeFilterSearchControl)control;
 }
 else if (control instanceof NameFilterSearchControl)
 {
 nameFilterSearchControl = (NameFilterSearchControl)control;
 }

Should I be looking into the attributes to filter for the users ?
