Boot into single user mode from cdrom. Mount your root filesystem and then
edit /etc/pam.conf or replace it with the unmolested backup copy you
invariably made before the edits. :)
Something like, from the OBP...
ok> boot cdrom -s
Machine boots from the Solaris CD.
# (Assuming no metadevices or anything are involved)
mount /dev/dsk/c0t0d0s0 /tmp/a
cp pam.conf pam.conf.broken
cp pam.conf.orig pam.conf
You exact detail may vary but that's the rough idea.
