*sigh*, investigating the issue further I realized this was due to a stupid mistake on my part. Sorry for the noise, -Martin On Fri, Nov 16, 2018 at 8:11 PM Martin Gignac <martin.gignac@gmail.com> wrote:
Hi,
I'm currently in the process of integration FreeRADIUS with 802.1x (EAP-TTLS/PAP) and FreeIPA (LDAP). If I don't perform group membership checking credential verification is working just fine. But when I try to validate membership of a user to an LDAP group it's failing during the check of the "groupOf" attribute. The user I am testing ( *"uid=rolo,cn=users,cn=accounts,dc=example,dc=org"*) is member to many groups (*"cn=XXXX,cn=groups,cn=accounts,dc=example,dc=org"*) in FreeIPA, and also has admin rights to the server so has many entries in the style *"cn=Replication Administrators,cn=privileges,cn=pbac,dc=example,dc=org"* (for example).
As FreeRADIUS goes down the list of groups to resolve the DN to a group name for comparison it seems to hit a wall with the second entry in the list. I thinking it could be because of the space in the first CN portion. It then returns the message *"ERROR: Group DN "cn=Replication Administrators,cn=privileges,cn=pbac,dc=example,dc=org" did not resolve to an object"*.

Using a standard 'ldapsearch' on the command line I *am* able to retrieve the *"cn=Replication Administrators,cn=privileges,cn=pbac,dc=example,dc=org"* object successfully, so I'm not sure why it said it does not resolve to an object.
I tried taking a look at src/modules/rlm_ldap/groups.c and src/modules/rlm_ldap/ldap.c but, not being a C programmer, I got lost fairly quickly.
Is it the space that's causing the error (that's all I can see)?
Thanks, -Martin
