The connector additionally ingests the entry management record (ACL) info for every doc. The ACL info is used to point out search outcomes filtered by what a person has entry to.

Resolution overview

In our answer, we configure AEM as an information supply for an Amazon Kendra search index utilizing the Amazon Kendra AEM connector. Primarily based on the configuration, when the information supply is synchronized, the connector crawls and indexes all of the content material from AEM that was created on or earlier than a selected date. The connector additionally indexes the Entry Management Record (ACL) info for every message and doc. When entry management or person context filtering is enabled, the search outcomes of a question made by a person consists of outcomes solely from these paperwork that the person is permitted to learn.

You first should allow IAM Identification Heart and create a corporation to sync customers and teams out of your energetic listing. The connector will use the person identify and group lookup for the person context of the search queries.

Conditions

To check out the Amazon Kendra connector for AEM utilizing this submit as a reference, you want the next:

Arrange OAuth2.0

If you’re utilizing AEM On-Premise, setup OAuth2.0 to generate an SSL certificates with the intention to full the configuration of Amazon Kendra AEM connector.

The Adobe Granite OAuth 2.0 server implementation (com.adobe.granite.oauth.server) supplies the assist for OAuth 2.0 server functionalities in AEM.

Allow the OAuth Server authentication handler

By default, AEM received’t allow the OAuth Server authentication handler. To allow it, full the next steps:

1. To begin the AEM native occasion, go to http://localhost:<port>/system/console/configMgr/com.adobe.granite.oauth.server.auth.impl.OAuth2ServerAuthenticationHandler
2. Change the jaas.rating.identify worth to 1100 within the Adobe Granite OAuth Server Authentication Handler part and save the configuration.

The OAuth Server authentication handler is now enabled.

Register the OAuth shopper

Each exterior utility requires OAuth authentication to be registered as an OAuth shopper in AEM. To register the OAuth shopper, full the next steps:

4. Copy the shopper ID and shopper secret and preserve them protected.

The Granite OAuth Server helps the next grant sorts:

• Authorization code
• Refresh token
• JWT bearer token

For this submit, we use OAuth2.0 with the JWT grant kind.

The JWT bearer token is especially used for server-to-server integration. This can assist us allow the server-to-server integration with out the useful resource proprietor interplay; for instance, to retrieve or add information with out person interplay.

Generate the JWT token

Full the next steps to generate the JWT token:

1. Navigate to localhost and the OAuth shopper.
2. Select Obtain Non-public Key.
3. Select Obtain.

Generate the general public certificates

Now, generate the general public certificates from the downloaded personal key, run the next command, and enter the personal key password.

Use the openssl command to generate the personal key:

>openssl pkcs12 -in retailer.p12 -out retailer.crt.pem -clcerts -nokeys

Extract the personal key:

openssl pkcs12 -in retailer.p12 -passin cross:notasecret -nocerts -nodes -out retailer.personal.key.txt

Make certain to put in openssl and add to the surroundings path beforehand.

Earlier than utilizing the personal key whereas configuring the Amazon Kendra knowledge supply, be certain that to not use or copy “-----BEGIN PRIVATE KEY-----” and “-----END PRIVATE KEY-----“ within the code. Moreover, take away any empty areas from the personal key.

Use the generated ClientId, ClientSecret, and personal key to configure the Amazon Kendra AEM knowledge supply.

For OAuth shopper registration, navigate to http://localhost:<port>/libs/granite/oauth/content material/purchasers.html.

Arrange SSL

Full the next steps to arrange SSL:

1. Create the important thing:

openssl genrsa -aes256 -out <keyFileName>.key 4096

2. Encrypt the important thing:

openssl req -sha256 -new -key <keyFileName>.key -out <keyFileName>.csr -subj '/CN=<keyFileName>'

3. Signal the important thing:

openssl x509 -req -days 365 -in <keyFileName>.csr -signkey <keyFileName>.key -out <keyFileName>.crt

4. Encode the personal key to der format:

openssl pkcs8 -topk8 -inform PEM -outform DER -in <keyFileName>.key -out <keyFileName>.der -nocrypt

4 information will likely be generated with file names beginning with <keyFileName>. We use <keyFileName>.crt and <keyFileName>.der in later steps.

5. Subsequent, log in to AEM at http://localhost:<port>/aem/begin.html.
6. Select Instruments, Safety, and SSL Configuration.
7. Within the Retailer Credentials part, enter the important thing retailer and belief retailer password.

Now, let’s import the certificates into the keystore path utilizing the important thing device.

12. Open a terminal and go to the folder location the place privateKey.crt is current and run the next command:

keytool -import -trustcacerts -keystore <JAVA_HOME>/lib/safety/cacerts -storepass changeit -noprompt -alias yourAliasName -file privateKey.crt

Whereas crawling the AEM knowledge supply, the connecter would set the person e-mail ID as principal. If person’s e-mail ID shouldn’t be accessible, then the person identify could be set as a principal.

The next screenshot exhibits an instance with the person e-mail ID user-dev-2@amazon.com set as principal.

The next instance makes use of person identify user-dev-2 set as principal.

4. Now, let’s attempt to search the identical content material with the token of person user-dev@amazon.com, who shouldn’t be licensed to view this particular doc that appeared within the previous question outcomes.

This confirms that paperwork ingested by the Amazon Kendra connector for AEM honors the ACLs set by and inside AEM and these identical ACLs are being enforced on the search outcomes based mostly on utilized token.

Clear up

To keep away from incurring future prices, clear up the assets you created as a part of this answer. When you created a brand new Amazon Kendra index whereas testing this answer, delete it. When you solely added a brand new knowledge supply utilizing the Amazon Kendra connector for AEM, delete that knowledge supply.

Conclusion

With the Amazon Kendra Adobe Expertise Supervisor connector, your group can search pages and belongings securely utilizing clever search powered by Amazon Kendra.
