From the error, its clear that ACS is not able to find the user identity in the configured identity store under your access policy. Check your access policy.
Check the details of the log, whether ACS is trying to contact AD to retrieve username from the AD or not. Whether AD is reachable and shows joined and connected.
If you have multiple domain controllers in the domain then check to which domain controller ACS is joined to. If it is joined to remote domain controller then join it manually with your local domain controller using the below command in acs-config mode.
ad-agent-configuration dns.dc.<domain.name>: [hostname1],[hostname2] ...
ad-agent-configuration dns.gc.<domain.name>: [hostname1],[hostname2] ...
Sometimes due to delay in response from AD also causes this issue.

dear brother.
i have checked both the domain and acs configs there is no issues or errors.
the only things is that clients should authenticate after they logeding to their pc or laptop with their domain username and password, but after they login there is no network connectivity and dotx errors should inside ACS that they have been authenticated via the mac address so the mac address comes to their username and password section.
but when i shutdown and unshutdown the interface they login and dot1x works fine for them so can you tell me what could be the problem brother.
see attached files for more info also my lan card properties for Dot1x authetication is that when client login it should take its autheticatioin from logeding useranema nd password which is their current domain account and password.

This is a really confusing config. My suggestions:
Change order to 802.1x first, second MAB.
In the client config, change from User auth to "Computer AND User", then create an authz policy that matches computer authentications and possibly give them limited network access (so they can be allowed to perform a proper Active Directory login).
This is how you normally do wired 802.1x for domain PCs.
Any perticular reasons why you want MAB as primary method?
