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.

Group Membership - Enforce Case Sensitivity

Sets whether group membership decisions are case sensitive. When a user or group is inferred (by not specifying or user or group search base or user identity attribute or group name attribute) case sensitivity is enforced since the value to use for the user identity or group name would be ambiguous. Defaults to false.

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)
