Restricting Access by Group Membership

jp-2
Setup:
FreeRADIUS 1.0.4 on FreeBSD 4.11 authenticating to eDirectory on Netware 6.5 server.

Issue:
I have read the FAQ section regaring limiting access to specific groups
(http://freeradius.org/faq/#5.2), but I can't get it to work.  For one, I am not
entirely certain where to add the lines.  I have tried using the users file, but
this doesn't seem to work.  Two, I am not sure that I am using the right syntax.
 Here is what I have tried:

- adding the following lines to users file:

----snip-----
DEFAULT Group == "cn=remoteusers,o=services", Auth-Type := Reject
        Reply-Message = "Your account has been disabled"

DEFAULT Auth-Type = LDAP
-----snip-----


Here is the debug:

re: Restricting Access by Group Membership

jp-2
My fault...members of that group are DENIED access.  Now I get.

So, that leads me to another question.  How do I change the syntax so that users
are ALLOWED access if they are a member of the specified group?  I tried
changing the line in the users file to Auth-Type := Allow, but this didn't work.
 Unfortunately, I can't find anything on this in rlm_ldap or FAQ.

Thanks in advance,

Josh

Just think backwards.

DEFAULT Ldap-Group == "cn=remoteusers,o=services"

DEFAULT Auth-Type := Reject
        Reply-Message = "Your account has been disabled"


That will see if you match Ldap-Group, if not, you won't match that line
in the users file so it will try the next line.  The next line rejects
everyone.

re: Restricting Access by Group Membership

In reply to this post by jp-2
Hi,
   To allow access the (regardless of password) you can set Auth-Type
:= Accept (See FreeRADIUS FAQ 5.5). I am not sure that is what you want
though, as in this case irrespective of what password a user enters he
will be granted access. You can use the configuration suggested by Dusty
Doris. That should work for you.

My fault...members of that group are DENIED access.  Now I get.

So, that leads me to another question.  How do I change the syntax so
that users
are ALLOWED access if they are a member of the specified group?  I
tried
changing the line in the users file to Auth-Type := Allow, but this
didn't work.
 Unfortunately, I can't find anything on this in rlm_ldap or FAQ.

Thanks in advance,

Josh

-----Original Message-----
Setup:
FreeRADIUS 1.0.4 on FreeBSD 4.11 authenticating to eDirectory on
Netware 6.5 server.

Issue:
I have read the FAQ section regaring limiting access to specific
groups
(http://freeradius.org/faq/#5.2), but I can't get it to work.  For one,
I am not
entirely certain where to add the lines.  I have tried using the users
file, but
this doesn't seem to work.  Two, I am not sure that I am using the
right syntax.
 Here is what I have tried:

- adding the following lines to users file:

----snip-----
DEFAULT Group == "cn=remoteusers,o=services", Auth-Type := Reject
        Reply-Message = "Your account has been disabled"

DEFAULT Auth-Type = LDAP

Here is the debug:
