CAS offline operation through DCE caching

If the device loses its connection to the DCE server, it enters into "offline" mode. At this point, the device can still authenticate user credentials against its own internal cache, if enabled. Users whose credentials match a previously cached set are granted device access; if the credentials do not match, the users are denied access. In offline mode, card swipe capabilities may not function.

To enable Login caching for offline mode, do the following:

  1. Log in Equitrac Web Client and navigate to System Configuration > Global Configuration Settings > User authentication. The User Authentication configuration dialog opens.
  2. In the CAS offline behavior section, select the Login caching from the DCE servers drop-down list.
    • Disabled: The Client follows offline behavior settings; the regular rules for cached only and allow all apply.
    • Enabled: The Client attempts to authenticate users with data cached on the DCE.

    DCE login caching determines whether a user login is accepted or denied when CAS is offline. If DCE caching is disabled when CAS is offline, then users cannot login. If DCE caching is enabled when CAS is offline, then DCE allows users to login only if they had previously logged in when CAS was online.

    For example, if DCE caching is enabled, and User1 authenticated while CAS was online, but User2 did not, then if CAS goes offline, User1 can still login, but User2 cannot login until CAS comes online again. Once CAS is back online, then User2 can login, and continue to login even if CAS goes offline again.

    Account limits are not enforced, and Billing Codes are not validated when DCE is operating without a connection to CAS.
  3. Select how DRE servers handle print jobs when CAS is offline.
    • Auto select: If account limits are enforced, then the Do not print option is used. If account limits are not enforced, then the Print, charge accounts later option is used.
    • Do not print: Users cannot print, and must wait until CAS is back online in order to print.
    • Print, charge accounts later: Users can print, and then the print job is charged to their account when CAS is back online.
