Accurate System Date and Time SettingsAccurate System Date and Time Settings
RSA Authentication Manager requires accurate date and time settings for replication and authentication. If the token clock and the Authentication Manager system clock do not match, the generated tokencodes will not match, and authentication attempts can fail. Specifying a Network Time Protocol (NTP) server for the instance prevents replication and authentication issues that are caused by clock drift.
Note: An NTP server is required in a replicated deployment. RSA requires that all Authentication Manager instances have their time synchronized to an NTP server.
If you do not specify an NTP server in Authentication Manager, the virtual appliance uses the date and time provided by the physical machine hosting the virtual appliance. In this situation, the physical machine hosting the virtual appliance should be configured to obtain accurate date and time information from an NTP server.
Make sure that you have the hostname or IP address of an NTP server before running Quick Setup.
