Hi,

did you already checked this

Security advisory: Badlock Bug

Yesterday, on April 12th, 2016, a new security bug named Badlock, has been disclosed. The bug affects almost all current Samba releases. Official site: http://badlock.org Red Hat and CentOS already released the updates: https://access.redhat.com/security/vulnerabilities/badlock Be aware that updating current NethServer installations could potentially lead to problems if Samba is configured in PDC mode and Windows workstations have joined the domain. ATTENTION Actually all Windows machines …

and this?

Nethserver and Badlock

Just wondering if Nethserver will be patched sometime in the next 2 weeks or so against Badlock ( http://badlock.org/ )?

Edit:
In short. Sounds like the Badlock-Problem. Did you updated recently?
If yes: Downgrade the Samba-Components using this command:
yum downgrade samba* tdb-tools libtdb libtevent libtalloc pytalloc libldb
