Warning: This page deals with one of the vague Policy Server flags and assumes certain level of familiarity with the dark soul of CA SiteMinder.
Is is pretty hard to understand the meaning of the
DisallowForceLogin registry key for SiteMinder Policy Server from the official documentation, even when you have plenty of time and manuals. This page pretends to summarize all that you may need to know about it, should you have to deal with this functionality some day.
History and Functionality
In a pre-R6 environment, when a user submits a password change request that contains an invalid current password, the Password Change Information screen appears with a message stating that the old password is incorrect. The user can provide the correct credential and change the password.
In R6 and R12, the Policy Server redirects the user to the login screen without the message (that is, ”forces login screen”). Enabling the
DisallowForceLogin registry key allows the old behavior in a new environment. When enabled, the Policy Server properly redirects users who have submitted a password change request that contains an invalid current password to the Password Change Information screen. This screen displays the invalid current password message. When disabled, the Policy Server redirects users to:
- The login page that does not display the invalid current password message. This redirect occurs if an
On-Auth-Reject-Redirectresponse is not bound to the policy configured with the user directory.
- The URL associated with the
On-Auth-Reject-Redirectresponse bound to the policy configured with the user directory
According to R6SP5 README, there are three cases affected by the
- Force password change or password expired.
- Self Password change.
- Optional password change.
