pam_ldap and 802.1x environment

[Thorsten Scherf]

Hey,

this is a comprehension question. When I have a ldap directory to
authenticate users with pam_ldap when they login to their local
workstations, how can I secure network access with radius?! I mean,
isn't that a chicken egg problem? How would I be able to talk to the
ldap server before I sucessfully authenticated against Radius? For sure
I do miss something, would be great if somebody could enlighten me. :)
