Grouper Users - Open Discussion List

[Lutz Suhrbier <>]

Hello,

meanwhile, I found a solution to that error.
Within the sources.xml, I have had to include at least those LDAP 
elements within "attribute" elements, which are requested in the 
subject, subjectId and description items of the source. If not, then the 
error described in my last posting (see below) occures.

As the wiki documentation states, that NOT including "attribute" 
elements just leads to requesting all available attributes from the 
given LDAP-source, this would mean that there is a bug in the 
implementation, or not ?
Or, is it a feature of the implementation, since looking through the 
documentation, I did not found a hint that Grouper-UI can be configured 
somewhere else as in sources.xml to define those attributes from the 
sources, which shall be presented to the user in the UI ?

best regards
Lutz
