While preparing the test cases for ITS#7381 (q.v.) I encountered two
issues when trying to add an instance of olcLDAPConfig below the chaining
overlay entry. If the instance entry looks like this...
dn: olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config
objectClass: olcLDAPConfig
objectClass: olcChainDatabase
olcDatabase: {0}ldap
...adding the entry (with ldapadd) fails with Error 65 (Object class violation).
The server logs the following:
504717ff slapd-chain: subsequent underlying database "olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config" must contain attribute "olcDbURI".
504717ff conn=1000 op=2: config_add_internal: DN="olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config" no structural objectClass add function
Note that converting a minimal chaining configuration with slaptest generates an
olcLDAPConfig entry without an olcDbURI, and that olcDbURI is not listed as a
MUST attribute for olcLDAPConfig.
Furthermore, if I try to add an olcLDAPConfig entry with an empty olcDbURI...
dn: olcDatabase={0}ldap,olcOverlay={0}chain,olcDatabase={-1}frontend,cn=config
objectClass: olcLDAPConfig
objectClass: olcChainDatabase
olcDatabase: {0}ldap
olcDbURI: ""
...it triggers an assertion:
slapd: chain.c:224: ldap_chain_uri_cmp: Assertion `li2->li_bvuri != ((void *)0)' failed.
Should I file an ITS for those two issues (or maybe two separate ITSs), or is this a
"don't do that" scenario?
