Can't load LDAP groups 3.0.7

[Dave Aldwinckle]

Hi All,

I am trying to reconfigure from version 2.1.12 to 3.0.7 and I am having 
an issue checking LDAP groups in the post-auth section.

I'm doing EAP-PEAP for authentication, and I want to check for group 
membership in post-auth, and assign a VLAN. I've tried putting the check 
in post-auth of "inner-tunnel" as well as post-auth of "default". The 
result was the same. I'm expecting to see a comparison of all the users 
groups with the one I have specified, but that does not occur.

I do see a successful search for the user:

rlm_ldap (ldap): Reserved connection (4)
(8) ldap: EXPAND (samaccountname=%{%{Stripped-User-Name}:-%{User-Name}})
(8) ldap:    --> (samaccountname=daldwinc)
(8) ldap: Performing search in "x" with filter "(samaccountname=user1)", 
scope "sub"
(8) ldap: Waiting for search result...
(8) ldap: User object found at DN "CN=David A (x),x"
(8) ldap: Processing user attributes
(8) ldap: WARNING: No "known good" password added. Ensure the admin user 
has permission to read the password attribute
(8) ldap: WARNING: PAP authentication will *NOT* work with Active 
Directory (if that is what you were trying to configure)

         basedn = "dc=x"

Debug excerpt (forgive me for not including the full output, its very 
cumbersome to sanitize.)

(8)   # Executing section post-auth from file 
/etc/raddb/sites-enabled/inner-tunnel
(8)     post-auth {
(8)       [ldap] = noop
(8)       if (ldap-LDAP-Group == group1 ) {
(8)       if (ldap-LDAP-Group == group1 )  -> FALSE
(8)     } # post-auth = noop


Thanks in advance,
Dave
