Hi, I'm facing crashes with openldap 2.4.30 (actually the RE24 of the day before
the release, but nothing changed in the meantime).
I have a consumer starting from scratch with an empty db. During his starting he
populates his db by connecting to 4 servers which are part of a 4-way
multi-master cluster. They are running a previous version of OpenLDAP.
We are doing an upgrade of our deployment just to solve an issue we face from
time to time consisting in data corruption.
This bug, which is not the target of this ITS, is able to trigger a crash of the
slave slapd 2.4.30.
During the first synchronization the consumer is receiving the entire db and I
can see on this slave, in the logs, coming two odd entries, like this one:
ldap15.log:Feb 28 15:45:02 ldap15 slapd[5219]: conn=-1 op=0:
memberof_value_modify DN="p?v#007" add
memberOf="cn=mynetbk,ou=allnetbk,ou=systems,ou=mygroups,dc=my_dc1,dc=my_dc2.it"
failed err=32
and after that slapd crashes.
I produced a core dump and generated the full back trace. And I can see this is
due to slapo-memberof.
This is my memberof configuration:
overlay memberof
memberof-group-oc groupOfNames
memberof-member-ad member
memberof-memberof-ad memberOf
memberof-dn cn=Manager,dc=my_dc1,dc=my_dc2.it
memberof-dangling ignore
memberof-dangling-error 80
memberof-refint FALSE
Here is the output. As I said, this output is taken from a slapd 2.4.30. The
platform is Linux x86_64.
