[Touch-packages] [Bug 1800462] [NEW] Request to add "ens" and "bond" interface to interface-order
Public bug reported: Can you please add new systemd interfaces "ens*" and "bond*" to interface-order? The interfaces are covered with the "*" in the last line, but IPv6 should be preferred to IPv4.

Title:
Segmentation fault on a slave slapd (sync replication with kerberos
authentication)
Status in openldap:
Fix Committed
Status in openldap package in Ubuntu:
In Progress
Bug description:
I have a slapd problem on a freshly installed 16.04 machine:
slapd[17107]: segfault at 1a ip 7f3c12c79f55 sp 7f3c03c2d080
error 4 in libsasl2.so.2.0.25[7f3c12c72000+19000]
I'm using the server as Slave LDAP-Server and sync replication with kerberos
authentication.
The service either starts and runs successfully or it fails with segmentation
fault or 100% CPU.
Maybe an useful info, I'm replicating two databases. When I deactivate
syncrepl for one of them (doesn't matter which one) the problem is not
occuring.

[Touch-packages] [Bug 921489] Re: Segmentation fault in slapd (related to GSSAPI?)
Hi Ryan, is a new bug really necessary, because the problem from this bug is really similar? apport is not possible but I can provider other reports if necessary. Maybe an useful info, I'm replicating two databases. When I deactivate syncrepl for one of them (doesn't matter which one) the problem is not occuring.
