I use the overlay constraint to check that a value of the attribute ssoRoles exists in the directory. The configuration looks like this:
Thanks for the report, fixed now in master
overlay constraint constraint_attribute ssoRoles uri ldap:///ou=applications,dc=cirra,dc=net?entrydn?sub?(&(objectClass=organizationalUnit)(ou:dn:=roles)) restrict="ldap:///ou=users,dc=cirra,dc=net??one?(objectClass=inetOrgPerson)"
An ldapmodify with this LDIF crash the slapd process:
dn: uid=toto,ou=users,dc=cirra,dc=net changetype: modify add: ssoRoles ssoRoles: ou=ROLE_PES,ou=roles,ou=simabo,ou=applications,dc=cirra,dc=net
The crash occurs because the entry uid=toto,ou=users,dc=cirra,dc=net do not exist. The same LDIF on an existing entry works well.
Below is the stacktrace generated with gdb:
