Doc Text:	Cause: Simple Paged Results did not supoort asynchronous search. Consequence: If the Directory Server received intensive asynchronous search requests, some of the requests failed and returned error 53 (LDAP_UNWILLING_TO_PERFORM). Fix: Asynchronous search support is implemented. Result: The Directory Server safely handles intensive asynchronous, simple paged result search requests.	Story Points:	---

Description Noriko Hosoi 2013-04-29 18:30:30 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47347

Some of the intensive asynchronous search requests fail with "unwilling to perform(53), Simple Paged Results Search already in progress on this connection".

Observed in 389-ds-base-1.2.11.15-11.el6.x86_64, but master also has the issue.

In the current code, SPR (simple paged results) is serialized and if a next page request comes in while the current page is being retrieved and returned, it returns 53 to the next page request.

Hi Noriko,
   To reproduce the issue - I need to run two parallel simple paged search and it should not return error 50. Please correct me if I am wrong.

The two searches need to be performed on the same connection using async LDAP calls.  You can't reproduce/verify the issue by simply running two separate search clients, as they will be using separate connections.  The original issue was encountered by SSSD, so you could use that as a client.  The alternative is to write a custom test client program.
