Trying to import a valid key + certificate bundle to PAM one gets a error about its contents and the certificate is not loaded
CA PAM all releases
One of the root causes for this is that the certificate part of the certificate + key file contains several certificates
Some Certification Authorities provide not only the final certificate but also the certificates of the certification authorities in the certification path. However, CA PAM is able to deal with only one certificate, so if it finds more than one in the file being loaded it error out
Make sure that the cettificate + key file contains a single certificate, not a chain of certificates, besides the private key
