If you create a Microsoft Root Certificate Authority (CA) with Windows Server 2008 and create a CAPolicy.inf file, you have to remove the AlternateSignatureAlgorithm=1 for the certificate to work with the Cisco ASA 8.4(7). If the AlternateSignatureAlgorithm=1 is in the CAPolicy.inf file, the root certificate will be created with the algorithm = RSASSA-PSS. If you remove this from the CAPolicy.inf file, the algorithm will be RSA SHA.
I ran into this issue in a Microsoft guide. The notes does say that AlternateSignatureAlgorithm will not work with Windows XP client computers. I have also seen that it will not work with Windows 2003 servers.
When trying to add a CA to the ASA from ASDM, this is the error:

I am discovered the same issue :( Answer: add to registry on CA this file:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CertSvc\Configuration\%NameCA%\CSP]
"ProviderType"=dword:00000000
"Provider"="Microsoft Software Key Storage Provider"
"HashAlgorithm"=dword:00008004
"CNGPublicKeyAlgorithm"="RSA"
"CNGHashAlgorithm"="SHA1"
"AlternateSignatureAlgorithm"=dword:00000001
"MachineKeyset"=dword:00000001
and renew Root CA & IssuingCA certificates
