Hello Ondřej! Thanks for the recommendation, Was not able to test this until now since this appears to be random and I have not been able to force the issue.
I now tested what you mentioned in a failed Consumer, and the search works fine and returns all the data, whether I do the search on the Provider or the Consumer slapacl also returns no issues.
Everytime I look at this issue I get more and more confused.
