Sorry I was quite busy...
No unfortunately it is not solved.
Advanced Auth had the Feature as displayed in the screenshot:
Search Type: Certificate: Specifies that the system searches for a certificate stored in the user's profile in the remote LDAP database.

So, ACA was checking in the LDAP DB if there's a cert stored in the users profile.
How can this be done with APM? I couldn't find any solution for it since it is more an active LDAP query which has to be done and not checking session variables.

Thanks,
Peter

Hello again,
The customer just told me that with ACA they could validate the provided cert against users cert stored in LDAP.
So, what is missing in the access profile is the ability to check the from the client provided cert with the cert stored at the user in LDAP.
The customer was using a cert validation with ACA if the provided cert is matching the user certs stored in LDAP, even when the user has two valid certs and one of it will soon be invalid because of the expired date.

  Have you used the APM VPE? I think you can do a simple LDAP search to get the contents of this, but you will need your full DN to set it.

    Hi AubreyKingF5 ,
    It was not possible to use the same features like in ACA.
    The problem is that we only have the action "Client Certificate is valid" but no "Client Certificate is available" like in ACA.

    ACA:
    Even with the flexibility of APM we couldn't get to the point to have the same functionality like ACA.
    The only possible way would be to use iRuleLX (NPM) but this would be quite complicated and questionable if it also works with the high traffic volume they have here at the customer.
