1. Ensure that the attribute returned from the SAML authentication source is able to be mapped directly to an RSA Identity Governance and Lifecycle user attribute value that corresponds to the same user.  
2. Enter the correct value in the SAML configuration page for the UnifiedUserColumn.  The column names can be chosen from any value user column in the table T_MASTER_ENTRERPRISE_USERS.  Possible columns that may be used include but are not limited to USER_ID, EMAIL_ADDRESS, or any custom user attributed mapped to a a local user attribute such as CUS_ATTR_USER_CAS_15 that has as its value the same value as the attribute returned in the SAML assertion. Note that the user must be a valid user.
