LdapUserGroupProvider

Another option for the UserGroupProvider is the LdapUserGroupProvider. By default, this option is commented out but can be configured in lieu of the FileUserGroupProvider. This will sync users and groups from a directory server and will present them in the NiFi UI in read only form.

The LdapUserGroupProvider has the following properties:


Property Name	Description
`Group Member Attribute - Referenced User Attribute`	If blank, the value of the attribute defined in `Group Member Attribute` is expected to be the full dn of the user. If not blank, this property will define the attribute of the user ldap entry that the value of the attribute defined in `Group Member Attribute` is referencing (i.e. `uid`). Use of this property requires that `User Search Base` is also configured. (i.e. `member: cn=User 1,ou=users,o=nifi` vs. `memberUid: user1`)
`Authentication Strategy`	How the connection to the LDAP server is authenticated. Possible values are `ANONYMOUS`, `SIMPLE`, `LDAPS`, or `START_TLS`.
`Manager DN`	The DN of the manager that is used to bind to the LDAP server to search for users.
`Manager Password`	The password of the manager that is used to bind to the LDAP server to search for users.
`TLS - Keystore`	Path to the Keystore that is used when connecting to LDAP using LDAPS or START_TLS.
`TLS - Keystore Password`	Password for the Keystore that is used when connecting to LDAP using LDAPS or START_TLS.
`TLS - Keystore Type`	Type of the Keystore that is used when connecting to LDAP using LDAPS or START_TLS (i.e. `JKS` or `PKCS12`).
`TLS - Truststore`	Path to the Truststore that is used when connecting to LDAP using LDAPS or START_TLS.
`TLS - Truststore Password`	Password for the Truststore that is used when connecting to LDAP using LDAPS or START_TLS.
`TLS - Truststore Type`	Type of the Truststore that is used when connecting to LDAP using LDAPS or START_TLS (i.e. `JKS` or `PKCS12`).
`TLS - Client Auth`	Client authentication policy when connecting to LDAP using LDAPS or START_TLS. Possible values are `REQUIRED`, `WANT`, `NONE`.
`TLS - Protocol`	Protocol to use when connecting to LDAP using LDAPS or START_TLS. (i.e. `TLS`, `TLSv1.1`, `TLSv1.2`, etc).
`TLS - Shutdown Gracefully`	Specifies whether the TLS should be shut down gracefully before the target context is closed. Defaults to false.
`Referral Strategy`	Strategy for handling referrals. Possible values are `FOLLOW`, `IGNORE`, `THROW`.
`Connect Timeout`	Duration of connect timeout. (i.e. `10 secs`).
`Read Timeout`	Duration of read timeout. (i.e. `10 secs`).
`Url`	Space-separated list of URLs of the LDAP servers (i.e. `ldap://<hostname>:<port>`).
`Page Size`	Sets the page size when retrieving users and groups. If not specified, no paging is performed.
`Sync Interval`	Duration of time between syncing users and groups. (i.e. `30 mins`). Minimum allowable value is `10 secs`.
`User Search Base`	Base DN for searching for users (i.e. `ou=users,o=nifi`). Required to search users.
`User Object Class`	Object class for identifying users (i.e. `person`). Required if searching users.
`User Search Scope`	Search scope for searching users (`ONE_LEVEL`, `OBJECT`, or `SUBTREE`). Required if searching users.
`User Search Filter`	Filter for searching for users against the `User Search Base` (i.e. `(memberof=cn=team1,ou=groups,o=nifi)`). Optional.
`User Identity Attribute`	Attribute to use to extract user identity (i.e. `cn`). Optional. If not set, the entire DN is used.
`User Group Name Attribute`	Attribute to use to define group membership (i.e. `memberof`). Optional. If not set group membership will not be calculated through the users. Will rely on group membership being defined through `Group Member Attribute` if set. The value of this property is the name of the attribute in the user ldap entry that associates them with a group. The value of that user attribute could be a dn or group name for instance. What value is expected is configured in the `User Group Name Attribute - Referenced Group Attribute`.
`User Group Name Attribute - Referenced Group Attribute`	If blank, the value of the attribute defined in `User Group Name Attribute` is expected to be the full dn of the group. If not blank, this property will define the attribute of the group ldap entry that the value of the attribute defined in `User Group Name Attribute` is referencing (i.e. `name`). Use of this property requires that `Group Search Base` is also configured.
`Group Search Base`	Base DN for searching for groups (i.e. `ou=groups,o=nifi`). Required to search groups.
`Group Object Class`	Object class for identifying groups (i.e. `groupOfNames`). Required if searching groups.
`Group Search Scope`	Search scope for searching groups (`ONE_LEVEL`, `OBJECT`, or `SUBTREE`). Required if searching groups.
`Group Search Filter`	Filter for searching for groups against the `Group Search Base`. Optional.
`Group Name Attribute`	Attribute to use to extract group name (i.e. `cn`). Optional. If not set, the entire DN is used.
`Group Member Attribute`	Attribute to use to define group membership (i.e. `member`). Optional. If not set group membership will not be calculated through the groups. Will rely on group membership being defined through `User Group Name Attribute` if set. The value of this property is the name of the attribute in the group ldap entry that associates them with a user. The value of that group attribute could be a dn or memberUid for instance. What value is expected is configured in the `Group Member Attribute - Referenced User Attribute`. (i.e. `member: cn=User 1,ou=users,o=nifi` vs. `memberUid: user1`)

	Note
	Any identity mapping rules specified in nifi.properties will also be applied to the user identities. Group names are not mapped.
