List,

I'm setting up chaining. And I want to get errors, no referrals :) my olcDatabase looks like this:

olcDatabase={0}ldap,olcOverlay={1}chain,olcDatabase={1}hdb,cn=config objectClass: olcChainDatabase (auxiliary) objectClass: olcConfig (abstract) objectClass: olcDatabaseConfig (structural) objectClass: olcLDAPConfig (structural) objectClass: top (abstract) olcDatabase: {0}ldap olcDbIDAssertBind: bindmethod="simple" binddn="uid=lalalala" credentials="foo" mode="self" olcDbURI: ldap://example.com

here is this object's parent:

olcOverlay={1}chain,olcDatabase={1}hdb,cn=config objectClass: olcConfig (abstract) objectClass: olcOverlayConfig (structural) objectClass: top (abstract) olcOverlay: {1}chain

The problem is that I can't insert an olcChainReturnError attribute into it. The schema doesn't allow it. I tried to add the olcChainConfig objectClass to the olcDatabase={1} object, which requires me to fill in an extra attribute "olcOverlay" - I tried {1}chain and "chain" and  "{0}ldap" but either give me an error 65 "invalid structural object class chain".

You don't state what version of the code you're using. Using current HEAD code it works as intended; olcChainReturnError can be set as needed (I checked it using ldapmodify).

For example,

# {0}chain, {-1}frontend, config dn: olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config objectClass: olcOverlayConfig objectClass: olcChainConfig olcOverlay: {0}chain olcChainCacheURI: FALSE olcChainMaxReferralDepth: 1 olcChainReturnError: TRUE
