The syntax for sp_ldapadmin set_failback_interval is the following, where time_in_minutes is the value from -1 to 1440 minutes (24 hours):
sp_ldapadmin 'set_failback_interval', time_in_minutes
A value of 0 indicates that failing back is manual. That is, the housekeeper task does not attempt to automatically fails back the LDAP server. You must perform this task manually.
A value of -1 sets the fail over time interval to 15 minutes, the default.
