Is there any way to set the user passwords to expire after a certain period? For instance: I would like all users to change their passwords once a month.
Unfortunately there is no way to schedule user passwords to expire within Yellowfin. If your environment users LDAP to authenticate you could consider configuring your LDAP environment to expire user passwords after a certain amount of time. This would prevent users from logging into Yellowfin if they are unable to authenticate with the LDAP server.
Also, this is a pretty reasonable request, so I've gone ahead and opened an enhancement request:
TASK ID #201718.
As with all enhancements, it could be sometime before this task makes it into our development cycle for review/implementation.
Hopefully some of this information has been helpful. Please let me know if you have any questions/concerns.
