User authentication in applications

When a user logs into the Alvao applications, their identity is authenticated in one of the following ways:

Microsoft Entra ID (ME-ID) authentication - user accounts are primarily stored in Microsoft Entra ID (cloud).
Active Directory (AD) authentication - user accounts are primarily stored in Active Directory (on-premises).
Alvao authentication - user accounts are primarily stored in the Alvao database.

Each user is authenticated in only one way. AD authentication can be combined with Alvao authentication, i.e. some users can authenticate with AD and some with Alvao. ME-ID authentication cannot be combined, i.e. if Microsoft Entra ID authentication is enabled, all users must authenticate with AAD.

Caution:

If there are multiple users with the same username in Alvao, none of them will be able to log in. This applies, for example, to users with a username with a domain name (e.g. contoso.com\james) and without a domain name (james).
