I want to do a ssh login to a linux server with putty using certificate from my usb dongle. I had successfully tried ssh login with certificate if i generated the certificate from that ssh server itself but in this case, it is from ldap server.
Copying that x509 cert (either binary or PEM) into .ssh/authorized_keys asked for password instead of passphrase.
below is sshd_config configurations:
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL
Subsystem sftp /usr/libexec/openssh/sftp-server
is it in the configuration files or in the certificate?
