I have OpenLDAP 2.3-2.3.30 running over Debian Linux with a 2.6.18-4-686 kernel. When enabling the referential integrity overlay (refint), I then get a "segmentation fault" error message when initializing my test-bed database (about 300 entries), at the very end of the slapadd command.

Then, I can start the slapd daemon, but it crashes if I search an entry related to the refint overlay.

I also use the dynlist overlay which works fine, and I've tried to declare the refint overlay before or after dynlist, but it doesn't change anything.

As soon as I comment out the refint overlay related configuration directives, I don't have any problem.

Extract from my slapd.conf file:

modulepath /usr/lib/ldap moduleload back_bdb moduleload dynlist moduleload refint

sizelimit 500 tool-threads 1 backend bdb checkpoint 512 30

database bdb overlay dynlist dynlist-attrset groupOfURLs memberURL member

overlay refint refint_attributes memberof uniquemember

I've also try to have the refint only monitor either memberof or uniquemember, but it doesn't change anything. Also, adding the optional refint_nothing directive didn't help . Below, the debug trace when running slapadd :

<= key_change 0 => key_change(ADD,142) <= key_change 0 => key_change(ADD,142) <= key_change 0 => key_change(ADD,142) <= key_change 0 <= index_entry_add( 322, "uid=testuser,ou=people,dc=intra,dc=XXXX,dc=YY" ) success => entry_encode(0x00000142): uid=testuser,ou=people,dc=intra,dc=XXXX,dc=YY slapadd shutdown: initiated Segmentation fault
