Description Sankar Ramalingam 2009-07-22 12:02:52 UTC
Description of problem:
LDAP reports an error "Server does not support sorting", if no entries present in the Suffix DN.

How reproducible: Consistently

Steps to Reproduce:
1. Run a simple paged search for a suffix which doesn't have any entry or give a filter which doesn't match any of entry in the DN.
2. Observe the output of the paged search.
3. It shows "Server does not support sorting".
Expected results: Error message is misleading as Sorting is not implemented.

Comment 1 Noriko Hosoi 2009-07-22 18:33:20 UTC
Problem description:
It's a bug in server side sorting. If the search result candidate is NULL, sort control is not created.
ldapsearch -b "dc=test,dc=com" -x -S "cn" "(cn=*)" dn 
ldap_parse_sort_control: Requested LDAP control not found

git patch file for ldbm_search.c

Fix description:  When sort request control is given, even if the search result is NULL, sort response control should be created and passed to the client.  This change fixes it.
