I m trying to setup eap-tls 802.1x using ACS SE 18.104.22.168.4 , WLC & CA. The problem i m facing is with installing the CA certificate on ACS appliance. Tried everything from cisco docs but not able to install certificate as its giving " Unsupported private key file format." The steps whic i had performed are...
1) Generate Certificate Signing Request:
Certificate subject ---- CN=idea_acs_01
Private key file ---- privatekeyfile.pem
Private key password -- cisco
Retype private key password -- cisco
Key length --- 1024
Digest to sign with --- SHA1
Then coppied the certificate signing request from the right side & pasted it on CA using "advanced certificate request" & then "Submit a certificate request by using a base-64-encoded CMC or PKCS #10 file, or submit a renewal request by using a base-64-encoded PKCS #7 file" option on CA & pasted the output in Base-64-encoded
certificate request. Then issued the certificate from CA & downloaded it on my desktop & then from my desktop to FTP server.
Even made a file naming privatekeyfile.pem with the output got during Generating Certificate Signing Request & uploaded the same on FTP.
2)Install ACS Certificate:
Then downloaded the certificate certnew.cer from FTP server using Download certificate file option. And also Download private key file from the FTP & typed password cisco. But after Submiting it gives error:
"Unsupported private key file format."
m not able to get why this srror is comming. Even tried all the steps above changing the format of Private key file ie .pvk , .pk but its not working for me.
Can anyone guide me whats the issue. Thanks in advance..
