Hi ,
Are you looking Siteminder to restrict the number of Password Changes within a period or minimum age (ex. cannot change a password within 1 hr., 1 day, etc. of last password change or a maximum number of password changes within (ex. 1 hr., 1 day, etc.)?
Refer : https://communities.ca.com/ideas/235729639
But this can be set at the Database level .
Minimum password age
If an administrator sets a password for a user and wants that user to change the administrator-defined password, the administrator must select the User must change password at next logon check box. Otherwise, the user will not be able to change the password until the number of days specified by Minimum password age.
