openLDAP authorization with PAP authentication

I am very new to radius, and I
am having a problem configuring radius to authenticate by checking my
already running openldap server for authorization and then using PAP for
authentication. I am running a CentOS server where openldap is the
backed to a samba network authentication server. My comments here will
be posted in blue, radius debugging output in black, and security
changes to the output in red. I have two test runs of different
configurations but will also explain what I did throughout the the progression of my radius server
development. First I followed the directions on
"Deploying Radius" at
http://deployingradius.com/documents/configuration/pap.html. This lets
me know that the server is working, but does not have much information
about LDAP authentication and other sites I have looked over use
outdated information. So, throughout this process, I have kept track of
the changes that I have made, and saved the original configurations to
the files that I make changes to so that I can always start over again
if need be. After
the first test, I made changes to the /sites-available/default file to
uncomment the ldap line in the authorization section. I left the ldap
authentication line commented out because of further research describing
that it is not needed if I am just doing pap authentication. I used a
username and password that I know works for my network authentication. I
also made changes to the /modules/ldap file in order to connect to the
ldap database. The radius server had difficulties extracting
the userPassword from the ldap server, but pulled out the NT, LM passwords and the username just fine. I then made
one more change to the ldap module. I uncommented the line
"password_attribute = userPassword" and received the following results:

After
this failed attempt, I figured that PAP was not configured properly for
my ldap authentication so I made a change to the /modules/pap file:
"auto_header = yes". I tested this configuration and saw that PAP was
still trying to authenticate my SSHA password with CRYPT so I added
"encryption_scheme = "ssha" " to the pap module file. and get this
result:
