openLDAP authorization with PAP authentication

20 Jan 2012

      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outdated information.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:
