Our Solution

miniOrange provides Single Sign On (SSO) to any type of applications whether they are in the cloud or on-premise. With Single Sign-On, Office 365 can put its existing trusted IdP in charge of the authentication process. Active directory is configured as identity source within miniOrange, which is set as default identity source. Due to this authentication will happen against active directory credentials and appropriate user attributes such as immutable id will be fetched upon successful authentication against Active Directory credentials. After configuring the identity source, users present in Active Directory can login into the end user dashboard through their Active Directory credentials. In case user does not exist within miniOrange, the user is created on the fly and configured directory attributes are fetched and stored in the user profile.

Advantages of Single Sign On solution:

• User can login using single credentials, no need to remember different user names and passwords.
• User is created on the fly so no need to manually create user in miniOrange.
• Users can configure 2 Factor Authentication as part of the sign-on process. miniOrange supports 15+ two factor authentication methods.
