Re: [ntp:questions] Active Directory, NTP, time differential affecting services

2015-02-17 Thread james machado
You can set the AD servers to get their time from NTP as well. The systems you need to get NTP time will then be in sync with the AD servers and those that get their time from AD will be within the 5 minutes needed by Kerberos. James On Tue, Feb 17, 2015 at 9:42 AM, the.loqui...@gmail.com
