Hello All,

​

I have been following the Howtos on how to connect authelia to freeipa, and can now connect an authenticate without any issue.However, if i set the filter for a particular ldap group i get permission denied.My configuration is as follows:

Authelia bit:

authentication_backend:
disable_reset_password: false

ldap:
implementation: custom
url: ldaps://ipa.net.xpto:33636
timeout: 5s
start_tls: false
tls:
server_name: ipa.net.xpto
skip_verify: true
minimum_version: TLS1.2
base_dn: dc=net,DC=xpto
username_attribute: uid
additional_users_dn: CN=users,CN=accounts
users_filter: (&(|({username_attribute}={input})({mail_attribute}={input}))(objectClass=person))
additional_groups_dn: OU=groups
groups_filter: (&(member=uid={input},cn=users,cn=accounts,dc=net,dc=xpto)(objectclass=groupofnames))
group_name_attribute: cn
mail_attribute: mail
display_name_attribute: displayName
user: UID=authelia,CN=users,CN=accounts,DC=net,DC=xpto
password: "myveryawsomeanddificultpassword"

My configuration bit for the filters:

access_control:
default_policy: deny
rules:
# Rules applied to everyone
- domain: "``auth.mysite.com``"
policy: bypass

- domain: lab.mysite.com
subject: "group:netshare_kb.mysite.com"
policy: two_factor

If i remove the subject: "group:netshare_kb.mysite.com" i can authenticate without any issue.

For the log bits:

So, it shows that i can log-on without issues, but it also appears that it cannot find the group, netshare_kb.mysite.com but the group is valid and active with-in ipa. I can see using ldapsearch that the user is also within that group:

​

dn: cn=netshare_kb.mysite.com,cn=groups,cn=accounts,dc=net,dc=xpto
cn: netshare_kb.mysite.com
description: Acesso a KB
gidNumber: 848450507
ipaUniqueID: b10d7d2e-a765-11e6-b189-02002e0f7ea7
member: uid=nuno,cn=users,cn=accounts,dc=net,dc=xpto
objectClass: ipaobject
objectClass: top
objectClass: ipausergroup
objectClass: posixgroup
objectClass: groupofnames
objectClass: nestedgroup

What am i missing? I am on the latest freeipa and authelia versions.Thanks for your help
