Authentication Type

Use the Authentication > Authentication Type to configure how user logins are authenticated. GigaVUE-FM supports and authenticates users against the following authentication methods:

Local database configured in the User Management
External authentication server (LDAP, RADIUS, or TACACS+)
Third Party, which is the external identity provider.

In earlier software versions, you can prioritize the authentication protocols, where in, if one of the authentication mechanism fails GigaVUE-FM will automatically fallback to any of the other methods. Starting in software version 5.8.00, you can select only one of the authentication methods depending on your requirement. That is, you can select any one of the remote authentication methods or use the local authentication method or the external identity provider. This allows for enhanced security by maintaining the user names and passwords in a single location.

Note: If you cannot access GigaVUE-FM due to failure in authentication, you can use the special access provided (https://<fm ip address/dns name>/admin). This access is applicable only for local users with super admin privileges.
However, in case of remote authentication mechanisms, you can configure fall back within the same scheme of AAA authentication. For example, for RADIUS authentication, you can add multiple RADIUS servers, so that, if the first server is not reachable, the second is tried and so on.

When upgrading to release 5.8.00, GigaVUE-FM configures the authentication method that was configured with the highest priority in the previous release.

For Example:

In GigaVUE-FM Release 5.7.00 and Previous	In GigaVUE-FM Release 5.8.00 and further
RADIUS, TACACS+, LDAP are configured. RADIUS configured as first priority	RADIUS
RADIUS, LDAP are configured. LDAP is configured as first priority	LDAP

As part of software version 5.8.00, if authentication is done in the local server, then authorization is also performed locally. If authentication is done in the remote server, then authorization is also done at remote. Therefore, it is not required to configure extra roles for mapping purposes.

Configure Default User Group

For security reasons, the Default User Group option is not configured by default in GigaVUE-FM. If required, you can configure the Default User Group option to specify how the local and externally authenticated users can be granted privileges in GigaVUE-FM. If there are no valid GigaVUE-FM specific groups configured in the remote server but if a default user group is configured in GigaVUE-FM, then that group will be assigned. Otherwise, the user cannot login in to GigaVUE-FM without groups being configured.

Note: You are responsible for configuring the groups at the remote server in the specified format for TACACS+ and RADIUS servers. For LDAP, you must configure the list of groups for Group Base DN in GigaVUE-FM.

To configure Default User Group in GigaVUE-FM:

Click on the right side of the top navigation bar.
On the left navigation pane, select Authentication > Authentication Type. In the authentication type page that appears:

Select the required Authentication Type.
Set the Default User Group to one of the options:

Super Admin Group
Admin Group
User Group

Click Save.

Groups Configured in GigaVUE-FM Based on AuthMethod

The following table consists of examples with groups resolved in GigaVUE-FM based on the AuthMethod field:

Auth Method	Logged in User	Map Default UserGroup	Remote Roles/ Group Base DN (if configured)	Expected Group	Assigned Group	Notes
Local	test	-	-	fm_user	fm_user	The authMethod is 'LOCAL'. Therefore, the logged-in user's group will be assigned.
TACACS+	tacacsuser1	-	fm_admin	fm_admin	fm_admin	The role which has been assigned remotely will be assigned.
TACACS+	tacacsuser3	-	fm_non_exist_group [specified group Does not match any roles in FM]	-	-	If non-exist group is being assigned remotely, then that user cannot login into GigaVUE-FM. GigaVUE-FM will reject that user.
TACACS+	tacacsuser3	User Group	fm_non_exist_group [specified group Does not match any roles in FM]	User Group	User Group	If non-exist group is being assigned remotely, then GigaVUE-FM will check if Default User Group has been configured. If Default User Group is configured, then it will assign the same and allow the user to log in to GigaVUE-FM.
TACACS+	tacacsuser2	-	-	-	-	If there are no groups configured remotely and Default User Group is also not configured in GigaVUE-FM, then that user cannot log in to GigaVUE-FM. GigaVUE-FM will reject that user.
RADIUS	radiususer1	-	fm_admin	fm_admin	fm_admin	The role which has been assigned remotely will be assigned.
RADIUS	radiususer3	-	fm_non_exist_group [specified group Does not match any roles in FM]	-	-	If non-exist group is being assigned remotely, then that user cannot log in to GigaVUE-FM. GigaVUE-FM will reject that user.
RADIUS	radiususer3	User Group	fm_non_exist_group [specified group Does not match any roles in FM]	User Group	User Group	If non-exist group is being assigned remotely, then GigaVUE-FM will check whether Default User Group has been configured; If Default User Group is configured, then it will assign the same and allow the user to log in to GigaVUE-FM.
RADIUS	radiususer2	-	-	-	-	If there are no groups configured remotely and Default User Group is also not configured in GigaVUE-FM, then that user cannot log in to GigaVUE-FM. GigaVUE-FM will reject that user.
LDAP	ldapuser1	-	CN=FMQA-SSO,DC=hqdevtest,DC=com	fm_admin	fm_admin	The mapped group for the provided Group Base DN will be assigned to the logged in user.
LDAP	ldapuser2	-	CN=FMQA-SSO,DC=hqdev,DC=com	-	-	If there are no group mapped to the provided/associated GROUP BASE DN, then GigaVUE-FM will reject the user and will not allow the user to log in as well.
LDAP	ldapuser2	User Group	CN=FMQA-SSO,DC=hqdev,DC=com	User Group	User Group	If there are no group mapped to the provided/associated GROUP BASE DN, then GigaVUE-FM will check whether Default User Group has been configured; If so, it will assign the same and allow the user to login to GigaVUE-FM.
LDAP	ldapuser3	-	-	-	-	If the LDAP user is not associated to any GROUP in LDAP and it does not return any group, then GigaVUE-FM will reject the user and will not allow the user to login as well.
LDAP	ldapuser3	User Group	-	User Group	User Group	If the LDAP user is not associated to any GROUP in LDAP and it does not return any group, then GigaVUE-FM will check whether Default User Group has been configured; If so, it will assign the same and allow the user to log in to GigaVUE-FM.
