If a minimal chaining configuration is dynamically added to a consumer server in a provider/consumer pair running delta-syncrepl, it will stop working when the consumer is restarted. The configuration is modelled after the one used in test022 in the OpenLDAP source distribution:
Sorry this report was neglected for so long, and thanks for the excellent test case. This is now fixed in git master.
Tested against git master (721e46fe6695077d63a3df6ea2e397920a72308d) with the original use case and it works, thanks. However, slapd now segfaults if started with cn=config obtained by converting an existing chaining configuration from slapd.conf. Steps to reproduce, using the scripts from the archive attached to the original report:
Ah thanks. Previous commit changed too much. Fixed now in master.
$ make clean-all replica-chaining $ ./start-replica.sh # segfault
The crash is in chain_ldadd, and occurs because the first back-ldap instance in the converted configuration lacks an olcDbURI. I have attached a patch which inserts a dummy URI in the common parameter structure when it's allocated. This URI (ldap://0.0.0.0) should never match any actual referral, so the instance can only serve to initialize common parameters (which happens with the first instance anyway, if I understood the code correctly.)
