From 7940270b9fbebfa09b25c18198933b6a6b82b1d3 Mon Sep 17 00:00:00 2001 From: Rob Crittenden Date: Jun 13 2011 07:51:05 +0000 Subject: Remove root autobind search restriction, fix upgrade logging & error handling. There was no point in limiting autobind root to just search cn=config since it could always just modify its way out of the box, so remove the restriction. The upgrade log wasn't being created. Clearing all other loggers before we calling logging.basicConfig() fixes this. Add a global exception when performing updates so we can gracefully catch and log problems without leaving the server in a bad state. https://fedorahosted.org/freeipa/ticket/1243 https://fedorahosted.org/freeipa/ticket/1254 --- diff --git a/install/share/root-autobind.ldif b/install/share/root-autobind.ldif index e7bbc8d..ecce115 100644 --- a/install/share/root-autobind.ldif +++ b/install/share/root-autobind.ldif @@ -17,8 +17,3 @@ changetype: modify replace: nsslapd-ldapimaptoentries nsslapd-ldapimaptoentries: on -dn: cn=config -changetype: modify -replace: nsslapd-ldapientrysearchbase -nsslapd-ldapientrysearchbase: cn=config -
