Modify an existing PIN policy in Lync Server 2013

 

Topic Last Modified: 2012-06-19

You can use the PIN Policy tab to provide personal identification number (PIN) authentication to users who are connecting to Lync 2013 with IP Phones. To use PIN authentication, make sure that Enable PIN Authentication is selected in Web Service settings. For details, see Modify existing Web Service configuration settings in Lync Server 2013.

Follow these steps to modify a user-level or a site-level PIN policy.

  1. From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or assigned to the CsServerAdministrator or CsAdministrator role, log on to any computer that is in the network in which you deployed Lync Server 2013.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server 2013 administrative tools.

  3. In the left navigation bar, click Security and then click PIN Policy.

  4. On the PIN Policy page, click a policy, click Edit, and then click Show details.

  5. In Edit PIN Policy, in Minimum PIN length, type or select the minimum PIN length that you want to allow. The default minimum length is five digits.

  6. To be able to specify the maximum number of logon attempts before a user is locked out, select the Specify maximum logon attempts check box. If you do not select this option, the maximum number of allowed attempts is automatically determined based on the PIN length. By default, the maximum number of attempts is automatically determined.

  7. If you selected the Specify maximum logon attempts check box, in Maximum logon attempts, type or select the maximum number of logon attempts that you want to allow.

  8. To have PINs expire, select the Enable PIN expiration check box. If you do not select this option, PINs will never expire. By default, PINs never expire.

  9. If you selected the Enable PIN expiration check box, in PIN expires after (days), type or select the number of days after which PINs expire.

  10. In PIN history count, type the number of PINs that a user must create before the user can reuse a PIN. By default, users can reuse their PINs.

  11. To allow common patterns of digits in PINs, such as sequential numbers and repetitive sets of numbers, select the Allow common patterns check box. If you do not select this option, only complex patterns of digits are allowed. By default, only complex patterns of digits are allowed.

    importantImportant:
    We recommend that you do not allow common patterns.
  12. Click Commit.
