| Hadoop User Group Mapping LDAP Bind User Distinguished Name | Distinguished name of the user to bind to AD as for user authentication search/bind and group lookup for role authorization. For openLDAP based directories this should be a DN string, for Active Directory this can be just a username, combined with the "Active Directory Domain" value for login. For example username in the field and example.com in the active directory domain will result in the User Principal Name value of username@example.com being used to bind. If you put a UPM value here, do not over-configure the "active directory domain" field otherwise you will end up presenting username@example.com@example.com for binds.
AD will accept a UPN value or the DN value as a valid Bind DN;
An example of a Distinguished Name (DN): CN=cdh admin,OU=svcaccount,DC=example,DC=com

| Log and Query Redaction Policy | Note: Do not edit this property in the classic layout. Switch to the new layout to use preconfigured redaction rules and test your rules inline.Use this property to define a list of rules to be followed for redacting sensitive information from log files and query strings. Click + to add a new redaction rule. You can choose one of the preconfigured rules or add a custom rule. When specifying a custom rule, the Search field should contain a regular expression that will be matched against the data. If a match is found, it is replaced by the contents of the Replace field.Trigger is an optional field. It can be used to specify a simple string to be searched in the data. If the string is found, the redactor attempts to find a match for the Search regex. If no trigger is specified, redaction occurs by matching the Search regular expression. Use the Trigger field to enhance performance: simple string matching is faster than regular expression matching.Test your rules by entering sample text into the Test Redaction Rules text box and clicking Test Redaction. If no rules match, the text you entered is returned unchanged. |
