JD:You have all the information you need to debug your problem. It does
JD:require reading the debug output carefully. But you should really try
JD:to do that yourself first. As a said earlier, verify you're reading the
JD:exact same users file in both cases (the debug output will tell you
JD:what files are being read), If they are then look at your users file
JD:and determine why the user name is not matching, there is nothing magic
JD:about it, it should be straight forward. Still stumped? Then come back
JD:to the list for help.
hi john - thanks for the help. however, i've read the debug output about
50 thousand times and am just not seeing what is causing the problem,
other than it not finding the username in the /etc/raddb/users file when
trying to authenticate from a windows box. i mean, the debug output from
the authentication request shows the username to be "test" and there's
clearly a user named "test" in the users file. every place in the debug
output where it lists the username it's "test". there doesn't seem to be
any domain prepended to it.
when starting the server, the debug output shows the file 'modules/files'
is being instantiated:
Module: Instantiating module "files" from file /etc/raddb/modules/files
files {
usersfile = "/etc/raddb/users"
acctusersfile = "/etc/raddb/acct_users"
preproxy_usersfile = "/etc/raddb/preproxy_users"
compat = "no"
}
and the user/password is in the /etc/raddb/users file. if it weren't then
the linux authentication requests wouldn't be working either, right?
i'm not trying anything complicated. this setup is not using ldap, active
directory, and it's not talking to a database. it's just supposed to be
reading a plain-text username and password from the users file.
here's the full debug output:
