Synchronization frequency
The synchronization frequency can be configured up to 24 times per day and happens at 14 minutes past the full hour (at intervals depending on the frequency setting). Additionally, OneSpan Authentication Server Appliance verifies at five-minute intervals whether any synchronization profiles have changed and, if so, triggers a new synchronization immediately.
LDAP synchronization access privileges
The minimal permissions for a BIND DN user account should permit reading all user information in the configured search base.
