Alan, Thanks for the pointers. All examples discuss unix groups and I need to avoid using those. Can I create a file with several definitions like : Finance = userA,userB,userC Engineering = diffuserA,diffuserB,diffuserC and somewhere else have another definition like: Finance: Reply-Message = "Hello Finance user %u" Engineering: Reply-Message = "Hello Engineering user %u" and in users file, have userA Auth-Type := Local, User-Password == "A123", Group == "Finance" userB Auth-Type := Local, User-Password == "B123", Group == "Finance" userC Auth-Type := Local, User-Password == "C123", Group == "Finance" diffuserA Auth-Type := Local, User-Password == "A456", Group == "Engineering" diffuserA Auth-Type := Local, User-Password == "B456", Group == "Engineering" diffuserA Auth-Type := Local, User-Password == "C456", Group == "Engineering" I'd appericiate some help with achieving this.

I've seen several Q&A about local groups of users but they all refer to system groups (i.e. - /etc/group configuration). I'd like to have a Group definition that will include attributes that are common to all users that belong in this group.

See the FAQ, and "man rlm_passwd", which describes exactly this.

Ok. I've probably mis-read the documents. Can someone please provide an example of how to specify group membership to a user and then define return values for this group ? Thanks in advance, Ami On 8/24/06, Alan DeKok <aland@deployingradius.com> wrote:

The examples I pointed you to do NOT discuss Unix groups. Go read "man rlm_passwd".

Alan, I'm using the man rlm_passwd examples and the examples within radiusd.confand still I can't manage to make User-Group membership to work. Here's my config: in radiusd.conf : passwd MyGroup { filename = /etc/MyGroup format = "~Group-Name:::*,User-Name" hashsize = 50 ignoreislike = yes allowmultiplekeys = yes delimiter = ":" } # Similar configuration, for the /etc/group file.

Phil, Thanks for your help. Can you also explain what format should the users file use ? Currently, I've tried : Ami User-Password == "ami123" Service-Type = Framed-User, Framed-Protocol = PPP, Fall-Through = Yes FIGrp Auth-Type := Local, MyGroup-Name := FIGrp Reply-Message = "Hello from Group FIGrp, %u" DEFAULT Pool-Name := main_pool, Auth-Type := Local Fall-Through = Yes and my dictionary file has : ATTRIBUTE MyGroup-Name 3003 string while my /etc/FIGroup file has the following : FIGrp:Ami and my radiusd.conf has : passwd MyGroup { filename = /usr/local/etc/raddb/FIGroup format = "~MyGroup-Name:*User-Name" hashsize = 50 ignoreislike = yes allowmultiplekeys = yes delimiter = ":" } I'm still unable to see a match to the Group entry when I run radiusd -X but only to the user and to DEFAULT entries : users: Matched entry Ami at line 1 users: Matched entry DEFAULT at line 20 Thanks again, Ami On 8/28/06, Phil Mayers <p.mayers@imperial.ac.uk> wrote:

My /etc/MyGroup file :

No. The "," prefixing the key in the format means that more than one value exists in that field, separated by commas, like the /etc/group file. The man page is quite specific. Your file would need to read:

FIGrp:::Ami,John

The "man rlm_passwd" docs are pretty specific about that example:

"""Parse a file similar to the /etc/group file."""

If you're generating the file yourself, you can use a simpler format:

passwd mygroup { filename = /etc/mygroup format = "~Group-Name:*User-Name" hashsize = 50 allowmultiplekeys = yes }

...ands

Reply-Message = "Hello from Group FIGrp, %u"

':=' is not a comparison operator. Read the "man" page.

I've changed the ':=' operator to '==' , so my file looks like : FIGrp Auth-Type := Local, MyGroup-Name == FIGrp Reply-Message = "Hello from Group, %u" Is my comparison correct ? Am I right to try and match the attribute name (MyGroup-Name) with the actual group name (FIGrp) ? Should it be in the users file ? Thanks, Ami Alan DeKok.

Try "man 5 users". Man page names are only unique within section numbers. Alternatively, "man -a users" will show you all the pages calles users from each section in turn. You want to read and understand "man 5 users" carefully else you'll get nowhere with FreeRadius. Additionally I'd point out since you didn't know how to use "man" properly, you might need to check a basic primer on unix else your time with FreeRadius will be EXTREMELY frustrating. You said you had tried: Ami User-Password == "ami123" Service-Type = Framed-User, Framed-Protocol = PPP, Fall-Through = Yes FIGrp Auth-Type := Local, MyGroup-Name := FIGrp Reply-Message = "Hello from Group FIGrp, %u" DEFAULT Pool-Name := main_pool, Auth-Type := Local Fall-Through = Yes ...which is virtually all wrong. You want: Ami User-Password := "ami123" Fall-Through = yes DEFAULT MyGroup-Name == "FIGrp" Reply-Message = "Hello from group FIGrp", Fall-Through = yes DEFAULT Pool-Name := main_pool With the server properly configured, you should not need to set Auth-Type and will ALMOST CERTAINLY break things if you do. You don't use == to compare passwords, but use := to *set* the server-side copy. You don't use := to compare, you use ==, and group names never go on the left-hand-side - either usernames or DEFAULT. Hope that helps
