Well I tried to use the Solaris pam module pam_krb5 to authenticate against heimdal but I got the same problem that using heimdal kerberized telnet programs. I got an Authorization failed message. Frankly, I would like to know if is possible use the Solaris 8 pam_krb5 module against Heimdal. Thanks in advance Alberto Patiņo jalbertop@aranea.com.mx
