I understand that currently a user is unable to access SDP from multiple domains, however this is a single domain and these technicians do not have accounts in both the Domain and under Local Authentication.

When logging in through the iPhone App, the following error is received:

I would like to note that when attempting to log into the application using the Demo Site, the application does work.  

I should also mention that it is not possible to add the technicians to the Domain as the domain is for one specific customer and the Technicians are not members of this domain.

Thank you in advance for feedback and support...Scott
