Error signing client message (0x80004005) in ClientAuth.log


Yesterday I come across a native mode client which was not communicating with MP. When I check the Clientauth.log I noticed the following error. 

ClientAuth.log:
Error signing client message (0x80004005).
ClientIDManagerStartup.log:
RegTask: Failed to get certificate. Error: 0x80004005


I found that there were two client authentication certificates which match the certificate selection criteria. I removed one certificate from the client and the client started working properly. You can alternatively configure the site or the client installation properties to select any certificate that matches the creteria to fix this issue.

Can you be more specific on remove one cert and configure the site or the client installation properties?

It all depends on your environment. If it is required that there should be more than two client auth certs installed, then you have to use client installation properties.
