Haven't run into what you've described, but we do use the RADIUS
client PAM module as you've noted. Our /etc/pam.d/sshd looks like:

# PAM configuration for the Secure Shell service

# Read environment variables from /etc/environment and
# /etc/security/pam_env.conf.
auth       required # [1]
# In Debian 4.0 (etch), locale-related environment variables were moved to
# /etc/default/locale, so read that as well.
auth       required envfile=/etc/default/locale

auth       sufficient

# Standard Un*x authentication.
#@include common-auth

# Disallow non-root logins when /etc/nologin exists.
account    required

# Uncomment and edit /etc/security/access.conf if you need to set complex
# access limits that are hard to express in sshd_config.
# account  required

# Standard Un*x authorization.
@include common-account

# Standard Un*x session setup and teardown.
@include common-session

# Print the message of the day upon successful login.
# This includes a dynamically generated part from /run/motd.dynamic
# and a static (admin-editable) part from /etc/motd.
session    optional  motd=/run/motd.dynamic noupdate
session    optional # [1]

# Print the status of the user's mailbox upon successful login.
session    optional standard noenv # [1]

# Set up user limits from /etc/security/limits.conf.
session    required

# Set up SELinux capabilities (need modified pam)
# session  required multiple

# Standard Un*x password updating.
@include common-password

Hope that helps.
