Eliminate the Automatic Password Renewal-Portal (User Administration)
How can I elminate the automatic password renewal for a particular user?
The UME of the portal cannot be configured on a user by user basis - its an all or none type approach.
You can prevent password renewal for everyone using the following UME configuration option: ume.logon.security_policy.password_expire_days with the value 99999.
This effectively stops password expiry from the portal perspective but you need to understand that if you are using an external UME it may not have the same result.
