Thanks for the quick replay. No joy, however. I made the code change and then
experienced sudo simply hanging. I couldn't break out, either. So I killed my
ssh session. The built sudo *did* work after I'd received a token, however.
I also tried building only with the --with-ldap option (left out --with-pam)
and I still receive the "Memory fault" without pam support built...
Got a little couch potato?
