The user is authenticated by the User Directory where the email fields
has no value, then the user cannot get access to the application. The
email user attribute should be from the other User Directory.
Environment
Policy Server 12.52SP1
Resolution
In Federation Journey, you cannot get user attributes from more than 1
User Directory if you run Policy Server and AdminUI version prior to
12.8SP3 as related in communities (1).
If you upgrade the environment to 12.8SP3, then you'll benefit this
feature which will allow you to get the user authenticated in one User
Directory and the email value picked from a second User Directory
(2)(3).
Out of the Box, Policy Server has no functionality to validate if the
value of the email attribute is empty or not, and if empty to search
the next directory.
The expression are used as filter to check and process different
attributes for the "same" User Director as related in this community
(4).
The most probable way to search the user in the first directory, and
if the email value is null to search for it in the second directory
will be to create a Custom Assertion Generator Plugin, which will
avoid that error :

Re: SiteMinder Federation - how to retrieve attributes from 2 user
directories for a single assertion
Hello, In Federation you can not use Directory Mapping as you
could use for A standard SiteMinder integration (Authenticate in
directory A and authorize in directory B). You can not retrieve
attributes from multiple user directories. You can retrieve
attributes from the directory where you have been
authenticated. As krish04 told you, you can maybe archive that
by using a custom assertion plug-in generator. Hope it helps,
Julien.

Identity Mapping for Federation Partnerships
You can now configure the Identity Mapping feature in SAML 2.0
IdP SP partnerships. This feature allows you to perform user
authentication and authorization using different user
directories at IdP. Attributes are returned from the user
directory that authorizes a user. In Administrative UI, the
Configure Partnership step of partnership creation now includes
new fields to enable the feature.

Identity Mapping in SAML 2.0 Federation
Identity Mapping in a SAML 2.0 IdP -> SP federation partnership
lets you authenticate users with one user directory and
authorize them with another user directory at IdP. The assertion
attributes are returned from the user directory that authorizes
the user.
