Using InterSystems Security Functions
Two functions are provided for working with InterSystems IRIS passwords:
-
IrisSecureStart — Similar to IrisStart, but with additional parameters for password authentication. The IrisStart function is now deprecated. If used, it will behave as if IrisSecureStart has been called with NULL for Username, Password, and ExeName. You cannot use IrisStart if you need to use some form of password authentication.
-
IrisChangePassword — This function will change the user's password if they are using InterSystems authentication (it is not valid for LDAP/DELEGATED/Kerberos etc.). It must be called before a Callin session is initialized.
There are IrisSecureStart and IrisChangePassword functions for ASCII "A", Unicode "W", and Unicode "H" installs. The new functions either narrow, widen or "use as is" the passed in parameters, store them in the new Callin data area, then eventually call the IrisStart entry point.
IrisStart and IrisSecureStart pin and pout parameters can be passed as NULL, which indicates that the platform's default input and output device should be used.
