cisco ACS local-server

With the cisco ACS appliance  the local certificate is issued at  1year. If it should expire you can easily craft a new certificate that's self-signed or a CSR.

The steps are very simple under ;

System Administration > Configuration>  Local Server Certificates

1: Select the  certificate type with the correct CN/lifetime

2: ensure  you set the  new certificate to  be use for  EAP and webGui

3: issue a acs stop and a acs restart  after deleting the pre-existing local-server-certificate

4: confirm the new certificate is indeed being used;


mac-1093e90f35a4:~ kfelix$ gnutls-cli | grep expires
*** Fatal error: Error in the certificate.
*** Handshake has failed
GnuTLS error: Error in the certificate.
