# Local Fallback

Local Fallback enables Standard Authentication in addition to Active Directory (a hybrid mode). It should only be used where security is not an issue, as it exposes all the risks associated with Standard mode.

WARNING: Local Fallback mode is not recommended; use at your own risk.

Authentication mode selected | User name and password authentication maintained in: | Logins permitted | Security1 access level | User properties in local database2
--- | --- | --- | --- | ---
Standard
| User table in runtime.db3 | Only for users in User table | User table in runtime.db3 | Viewable
Active Directory
| AD | Only AD accounts | User must be also in User table in runtime.db3 | Present, when the database field name is not an AD field name. At display time AD named fields display AD value from AD, ignoring any field value that is in the local table.
Active Directory with Fallback
| AD and/or User table in runtime.db3 | Both | Both from above | Both from above

Note:

- 1: Use the CurrentAcessLevel field in User table or create your own fields to take advantage of this.
- 2: Depends on what field the user adds in addition to the defaults
