Playing around with the public beta for OES2018 I noticed that my
/etc/sudoers file does not work here. I get messages like

sudo: ../nptl/pthread_mutex_lock.c:82: __pthread_mutex_lock: Assertion
`mutex->__data.__owner == 0' failed.

The configuration is with password controlled access for groups of
administrative users managed in eDirectory, like:

The same configuration works on SLES12 SP2 with plain ldap
authentication instead of LUM as well as on previous OES versions. Did
anybody else notice this and would like to share her or his experiences?
