In the meantime I ran the test from the bug description.
Before the update:

ubuntu@xenial-slaps-segfault-1688575:~/test$ ./sasltest
rc = -6 (Unknown authentication method)

by the bug reporter during replication from a master to a slave, and can be

The fix is applied upstream, see comment #13.

Last I tried, I couldn't reproduce it. Can we make the case for an SRU
without a clear test case?

Oh, and I used libsasl2-modules-gssapi-mit and MIT kerberos KDC:

Just to be clear, I'm not doubting the bug, I'm just trying to come up
with a test scenario that will satisfy the SRU requirements so we can
ship the fix to xenial :)

Hm, I'm not getting a segfault.
I have two databases on the server: dc=example,dc=com and dc=example,dc=org.
Both have syncprov, and my slave is syncrepling from both using gssapi.
I created a replicator principal, added an ACL to allow it to read
everything in both trees.
I didn't use k5start
Thanks. I'm coming up with a test case simple enough to use for the SRU
template
