 #### Syncing roles at login
 
-You can also use the AUTH_ROLES_SYNC_AT_LOGIN configuration variable to control how often Flask-AppBuilder syncs the user's roles with the LDAP/OAUTH groups. If AUTH_ROLES_SYNC_AT_LOGIN is set to True, Flask-AppBuilder will sync the user's roles each time they log in. If AUTH_ROLES_SYNC_AT_LOGIN is set to False, Flask-AppBuilder will only sync the user's roles when they first register.
