Specific outgoing IP for syncrepl
by Dale Thompson - NOAA Federal 24 Apr '20

24 Apr '20

I've been using openldap's multi-master syncrepl based sync for years and it works great. But, I would like to be able to specify which IP on a multi-IP system syncrepl makes outgoing connections to other members of the sync cluster. On my multi-IP servers I am able to get slapd to only bind to a specific IP with the appropriate -h option. That works fine. But, outgoing syncrepl connections come from the primary IP on the server. Can anyone suggest a way to specify which IP syncrepl will use to make outgoing replication queries? -- Dale James Thompson, NWS Radar Operations Center IT Specialist, Configuration Management Team 1313 Halley Circle Norman, OK 73069 Voice (405) 573-3472 Fax (405) 573-3480 Dale.J.Thompson(a)noaa.gov

I don't know what you were reading or if it's even related to OpenLDAP. As I said, it's up to clients to follow referrals if one is returned. The ldap* clients do not follow referrals. If you want the consumer to forward updates to the provider on the writer's behalf, then you need to configure chaining as I already stated. --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>
