olcSyncrepl invalid URL - OpenLDAP 2.4.21

[Hung Luu <hung.n.luu@gmail.com>]

Hello everyone,

Has anyone experienced the "<olcSyncrepl> invalid URL" error from starting up a consumer slapd? I've tried configuring the provider setting for the syncrepl directive as a domain name and IP address but neither works.

Thanks in advance for your help.

Here's the error from slapd:

olcSyncrepl: value #0: <olcSyncrepl> invalid URL
config error processing olcDatabase={1}hdb,cn=config: <olcSyncrepl> invalid URL

Here's my consumer slapd.conf:
