The pam_env module is a big one, which is used by admins to configure
arbitrary environment settings for all sessions. The specific case that
prompted this had to do with proxy settings configured in the environment.

Other modules that may need to set environment variables include pam_krb5
and pam_afs_session, whose environment settings may be required for proper
filesystem access.
