I cannot deploy ESET Remote Administrator Agent to clients after updating Samba

Issue

Due to a known vulnerability in Samba (CVE-2016-2016) version 3.6.23-30.el6-7 and earlier, SMB signing is deactivated by default. This function is required for push installation of the ESET Remote Administrator (ERA) Agent. The following error will be displayed in the ERA Server trace log:

Connection failed: NT_STATUS_ACCESS_DENIED

Solution

A new version has been released
