The CorporateCustomClaimUuid property refers to the corporate custom claim that will be generated. This claim will be generated only if the user account contains the LDAP attribute defined in CustomClaimAttribute.
The value of the corporate custom claim is the value contained in the LDAP attribute. For example, in Active Directory, there is an attribute called title on every user account. If the title had the value SOFTWARE DESIGN ENGINEER and it was mapped this to a corporate custom claim called Occupation, you would get a corporate custom claim with Name = Occupation and Value = SOFTWARE DESIGN ENGINEER at runtime.
