yubico-pam: pam_yubico.so path (e.g. for sshd) #16313

Environment: (mips, 19.07)

Description:

In case anyone has the same problem trying to get yubico OTP based login to work for SSH login:

assuming you already installed openssh-server-pam and yubico-pam packages and configured PAM, SSH according to a guide like this: https://docs.termius.com/termius-handbook/yubikey-support
the missing piece to get it to work on openwrt if you are getting this error message Permission denied (keyboard-interactive) when trying to connect over ssh because of pam_yubico.so not being loaded is:
- in /etc/pam.d/sshd, add the absolute path to pam_yubico.so
  - original (based on guide): auth sufficient pam_yubico.so id=xxxxx debug authfile=/etc/yubico_pass
  - modified (openwrt support): auth sufficient /lib/security/pam_yubico.so id=xxxxx debug authfile=/etc/yubico_pass

I wasn't aware that libpam-yubico is available in source. Where did you find the sourcecode to compile pam_yubico.so for MIPS target?

See Sources link in: https://openwrt.org/packages/pkgdata/yubico-pam

The Makefile links to here: https://developers.yubico.com/yubico-pam/Releases/

I did not have to compile it myself as it’s already available in opkg
