Re: openldap 2.4.7 Segfault when deleting olcAccess parameter from cn=config
Faraz Khan wrote:
When trying to delete a single olcAccess attribute from cn=config the
openldap server crashes. The client library (php) returns error code -1
(cant contact LDAP Server) and the openldap server crashes.
The delete operation is:
dn: olcDatabase={2}bdb,cn=config
changetype: modify
delete: olcAccess
olcAccess: 2
This behavior is not consistent. Sometimes the server crashes while
sometimes it will report back :
modifying entry "olcDatabase={2}bdb,cn=config"
ldap_modify: No such attribute (16)
It might continue to say Error 19 for a while (3-4 times) and on the 5th
time the operation completes successfully. However, the dn at this time
seems to contain NO entries. After this slapd crashes. Restarting will
show that the operation was never ACTUALLY completed. The segfault trace
is:
