NiFi LDAP Cannot Locate Initial Admin

NiFi LDAP Cannot Locate Initial Admin

New Contributor

Hi.

 

We're trying to configure NiFi to require users to authenticate using their Active Directory credentials when accessing the UI. We've tried multiple permutations, but we always get an error message along the lines of "cannot locate Initial Admin Identity jane.doe".

 

We've already tried the following:

  • Comment out nifi.security.identity.mapping.pattern.dn in nifi.properties and specify the entire dn for the Initial Admin Identity
  • Modifying the User Identity Attribute to something other than cn

Can anyone think of a reason why we might be running into this issue?

 

Thanks,
Cory

        The FileUserGroupProvider will provide support for managing users and groups which is backed by a file
        on the local file system.

        - Users File - The file where the FileUserGroupProvider will store users and groups.

        - Legacy Authorized Users File - The full path to an existing authorized-users.xml that will be automatically
            be used to load the users and groups into the Users File.

        - Initial User Identity [unique key] - The identity of a users and systems to seed the Users File. The name of

        The LdapUserGroupProvider will retrieve users and groups from an LDAP server. The users and groups
        are not configurable.

        '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.

            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).

            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.

        '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'.

            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.

        The FileAccessPolicyProvider will provide support for managing access policies which is backed by a file
        on the local file system.

        - User Group Provider - The identifier for an User Group Provider defined above that will be used to access
            users and groups for use in the managed access policies.

        - Authorizations File - The file where the FileAccessPolicyProvider will store policies.

        - Initial Admin Identity - The identity of an initial admin user that will be granted access to the UI and
            given the ability to create additional users, groups, and policies. The value of this property could be
            a DN when using certificates or LDAP, or a Kerberos principal. This property will only be used when there
            are no other policies defined. If this property is specified then a Legacy Authorized Users File can not be specified.

            NOTE: Any identity mapping rules specified in nifi.properties will also be applied to the initial admin identity,
            so the value should be the unmapped identity. This identity must be found in the configured User Group Provider.

            not be specified, and this property will only be used when there are no other users, groups, and policies defined.

            NOTE: Any users in the legacy users file must be found in the configured User Group Provider.

        - Node Identity [unique key] - The identity of a NiFi cluster node. When clustered, a property for each node
            should be defined, so that every node knows about every other node. If not clustered these properties can be ignored.
            The name of each property must be unique, for example for a three node cluster:
            "Node Identity A", "Node Identity B", "Node Identity C" or "Node Identity 1", "Node Identity 2", "Node Identity 3"

            in the configured User Group Provider.

        - Node Group - The name of a group containing NiFi cluster nodes. The typical use for this is when nodes are dynamically
            added/removed from the cluster.

            NOTE: The group must exist before starting NiFi.

        '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>).
        'User Search Base' - Base DN for searching for users (i.e. CN=Users,DC=example,DC=com).
        'User Search Filter' - Filter for searching for users against the 'User Search Base'.
            (i.e. sAMAccountName={0}). The user specified name is inserted into '{0}'.

        'Identity Strategy' - Strategy to identify users. Possible values are USE_DN and USE_USERNAME.
            The default functionality if this property is missing is USE_DN in order to retain
            backward compatibility. USE_DN will use the full DN of the user entry if possible.
            USE_USERNAME will use the username the user logged in with.
        'Authentication Expiration' - The duration of how long the user authentication is valid
            for. If the user never logs out, they will be required to log back in following
            this duration.

# Identity Mapping Properties #
# These properties allow normalizing user identities such that identities coming from different identity providers
# (certificates, LDAP, Kerberos) can be treated the same internally in NiFi. The following example demonstrates normalizing
# DNs from certificates and principals from Kerberos into a common identity string:
#
# nifi.security.identity.mapping.pattern.dn=^CN=(.*?), OU=(.*?), O=(.*?), L=(.*?), ST=(.*?), C=(.*?)$
nifi.security.identity.mapping.pattern.dn=^CN=(.*?), OU=(.*?), OU=(.*?), OU=(.*?), DC=(.*?), DC=(.*?), DC=(.*?), DC=(.*?)$
nifi.security.identity.mapping.value.dn=$1
# nifi.security.identity.mapping.pattern.dn2=^CN=(.*?), OU=(.*?), O=(.*?), L=(.*?), S=(.*?), C=(.*?)$
# nifi.security.identity.mapping.value.dn2=$1
# nifi.security.identity.mapping.value.dn=$1@$2
# nifi.security.identity.mapping.transform.dn=NONE
# nifi.security.identity.mapping.pattern.kerb=^(.*?)/instance@(.*?)$
# nifi.security.identity.mapping.value.kerb=$1@$2
# nifi.security.identity.mapping.transform.kerb=UPPER
