Hi, I would like to use pam_krb5.so.1 on my login service I've put this at the top of my login stack in pam.conf: login auth required /usr/lib/security/pam_krb5.so.1 debug But when I try to login on the console the login fails and this appears in /var/adm/messages login: load_modules: can not open module /usr/lib/security/pam_krb5.so.1 For reference: ls -l /usr/lib/security/pam_krb5.so.1 -rwxr-xr-x 1 root sys 736984 Dec 5 10:20 /usr/lib/security/pam_krb5.so.1 I've tried pam_krb5 v1.0 and v 1.0.3, both fail with the same error. Any ideas as to what is going wrong? TIA. Shaun
