The Windows Search 4. To install Windows Search 4. Also, Terminal Services must be running for Windows Search 4. By default, Terminal Services is configured to start automatically. However, it may have been disabled manually or by third-party software. If Terminal Services is disabled, the installation of Windows Search 4. To determine the status of Terminal Services, and start the service if it is disabled, follow these steps:. If the installation of Windows Search 4.
Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help prevent any unauthorized changes to the file. Run the following commands. If this command does not run, troubleshoot your Anaconda installation.
Check that the correct nupack version is now installed by running the following commmand:. If the version is not correct, go back to Step 4, double-check the folder name, and rerun the command. You can launch a web-based Jupyter notebook browser from the command line:. If no browser window appears, try navigating to the displayed link in your terminal. If the same user also authenticates with a UPN version of the username, such as username example.
If, to assign authorizations, you rely on groups rather than individual user settings, all accounts that authenticate by using the same Windows user account should receive the same privileges. Regardless of whether the user prefixes the domain name, group mapping will assign the user to the same ACS user group, because both ACS user accounts correspond to a single Windows user account. Processing authentication requests for unknown users requires slightly more time than processing authentication requests for known users.
This small delay may require additional timeout configuration on the AAA clients through which unknown users may attempt to access your network. Adding external user databases against which to authenticate unknown users can significantly increase the time needed for each individual authentication.
At best, the time needed for each authentication is the time taken by the external user database to authenticate, plus some time for ACS processing. In some circumstances for example, when using a Windows user database , the extra latency introduced by an external user database can be as much as tens of seconds. If you have configured the Unknown User Policy to include multiple databases in unknown user authentication, the latency for which your AAA client timeout values must account is the sum of the time taken for each external user database to respond to an authentication request of an unknown user, plus the time taken for ACS processing.
You can reduce the effect of this added latency by setting the order of databases. If you are using an authentication protocol that is particularly time sensitive, such as PEAP, we recommend configuring unknown user authentication to attempt authentication first with the database most likely to contain unknown users who use the time-sensitive protocol.
For more information, see Database Search Order. You must increase the AAA client timeout to accommodate the longer authentication time that is required for ACS to pass the authentication request to the external user databases that an unknown user authentication uses. If the AAA client timeout value is not set high enough to account for the delay that an unknown user authentication requires, the AAA client times out the request and every unknown user authentication fails.
If you have ACS configured to search through several databases or your databases are slow to respond to authentication requests, consider increasing the timeout values on AAA clients. Although the Unknown User Policy allows authentication requests to be processed by databases that are configured in the External User Database section, ACS is responsible for all authorizations that are sent to AAA clients and end-user clients.
Unknown user authentication works with the ACS user group mapping features to assign unknown users to user groups that you have already configured and, therefore, to assign authorization to all unknown users who pass authentication.
The options for configuring the Unknown User Policy are:. Selecting this option excludes the use of the Check the following external user databases option. ACS does not support fallback to unknown user authentication when known or discovered users fail authentication. ACS attempts the requested service—authentication—by using the selected databases one at a time in the order that you specified.
For more information about the significance of the order of selected databases, see Database Search Order. This configuration affects the initial setting of the new dynamic user. The Unknown User Policy supports unknown user authentication. It will:. Find the next user database in the Selected Databases list that supports the authentication protocol of the request. If the list contains no user databases that support the authentication protocol of the request, stop unknown user authentication and deny network access to the user.
Send the authentication request to the database in Step 1. If the database responds with an Authentication succeeded message, create the discovered user account, perform group mapping, and grant the user access to the network. If the database responds with an Authentication failed message or does not respond and other databases are listed below the current database, return to Step 1. If no additional databases appear below the current database, deny network access to the user.
When you specify the order of databases in the Selected Databases list, we recommend placing as near to the top of the list as possible databases that:. As a user authentication example, if wireless LAN users access your network with PEAP, arrange the databases in the Selected Databases list so that unknown user authentication takes less than the timeout value that is specified on the Cisco Aironet Access Point.
Step 2 To deny unknown user authentication requests, select the Fail the attempt option. Step 3 To allow unknown user authentication, enable the Unknown User Policy:. Select the Check the following external user databases option. To assign the database search order, select a database from the Selected Databases list, and click Up or Down to move it into the position that you want.
Note For more information about the significance of database order, see Database Search Order. Clicking The database in which the user profile is held option permits subsequent authentications to work with the external database that cached the user.
Step 5 Click Submit. ACS processes unknown user authentication requests by using the databases in the order in the Selected Databases list. You can configure ACS so that it does not provide authentication service to users who are not in the ACS internal database.
Step 2 Select the Fail the attempt option. Step 3 Click Submit.
