  • NetIQ Access Manager 4.x install.sh script returns error:

    Starting ntp daemon...

    Terminating the installation.

  • The default installation of RedHat 7 Enterprise Server uses chronyd per default instead of xntp

Resolution


  • or modify the installation scripts which are locates within the "scripts" directory


  1. pre_install.sh:
    comment out the line “check_ntp”


  2. nam_rhel7_functions.sh and nam_rhel6_functions.sh
    remove remove “ntp” and “ntp*x86_64” from the RPM_LIST arrays

Additional Information

Access Manager requires time synchronization between all components. Access Manager Console servers are running eDirectory with a special schema in order to store configuration and federation information. As with any replicated database time synchronization is required. Authentication processes which use a valid to timer like a SAML assertion might fail if the time is not corrrect. The check for NTP with the install script tries to make sure time is correct
