attributeKeyName maybe not getting value from config?

[f1-outsourcing]

I have got it to work somehow by adding username to client scope mapper and entering these objectids[1].

I had to skip this error to continue.

817 if (in_array($attributeKeyName, array_keys($attributes))) {
818 if (!$allowRepeatAttributeName) {
819 //fix???
820 continue;
821 throw new ValidationError(
822 "Found an Attribute element with duplicated ".$keyName,
823 ValidationError::DUPLICATED_ATTRIBUTE_NAME_FOUND
824 );
825 }
826 }

The only problem I know have is I am redirected to home and not eg to wp-admin
