Hello,
We are currently getting some interesting accounting packets that are
coming in with User-Name of NULL. We would like to use rlm_rewrite to
change all NULL usernames to something else.
We are running freebsd 4.8 with freeradius .9.
Here is what I setup so far.
attr_rewrite noname {
attribute = User-Name
searchin = packet
searchfor = *
replacewith = "ihavenoname"
ignore_case = yes
new_attribute = no
max_matches = 10
append = no
}
* we have tried
"NULL"
"[^*$]"
"[^\\000$]"
Then in the accounting section we added noname
accounting {
noname
acct_unique
detail1
detail2
}
However, it doesn't seem to match when we send a User-Name attribute
with a NULL value. We tried it with radclient and sent
User-Name=""
User-Name=" "
The message we get is
rlm_attr_rewrite: Attribute User-Name string value NULL or of zero length
modcall[accounting]: module "nodomain" returns noop
I'm guessing that rlm_rewrite can't change a NULL User-Name setting
because its looking for something to change to something else.
We also gave a shot with preproxy_users, but it doesn't seem to be picked
up. Is that enabled in freeradius .9?
DEFAULT
User-Name := "ihavenoname"
The rlm_rewrite does work with a valid User-Name
rlm_attr_rewrite: Changed value for attribute User-Name from 'a' to
'ihavenoname'
modcall[accounting]: module "nodomain" returns ok
This was sending an accounting packet with User-Name of a.
Any ideas of anything else we could try, or perhaps a recent cvs snapshot?
Thanks
Dustin Doris
