      That's what I'm using :
      FreeRadius 0.15.7_27 and a MariaDB (== a mysql variant) on a server on my LAN to authentify captive portal users.

      I never used this :

      Try to create 'dumb' user on the FreeRADIUS / Users page and check again with radiusd -X

      Info : This "dumb" user will get stored in a file /usr/local/etc/raddb/mods-config/files/authorize (not the database).

        @aysman Please check this:

        1. killall radiusd
        2. open /usr/local/etc/raddb/sites-enabled/default
          and replace if ((notfound || noop) && (&control:Auth-Type != Accept)) {
          with if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept")) {
        3. run radiusd -X and check authentication again

          This works ..... but :
          I had to :

          #	files
#	if ((notfound || noop) && (&control:Auth-Type != Accept)) {
	if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept")) {

          => I exclude 'files' altogether.
          Now the 'radcheck' table is questionned :

          (0) eap: No EAP-Message, not doing EAP
(0)     [eap] = noop
(0)     if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept")) {
(0)     EXPAND %{%{Control:Auth-Type}:-No-Accept}
(0)        --> No-Accept
(0)     if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept"))  -> TRUE
(0)     if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept"))  {
(0)       redundant sql {
(0) sql1: EXPAND %{User-Name}
(0) sql1:    --> test
(0) sql1: SQL-User-Name set to 'test'
rlm_sql (sql1): Reserved connection (1)
(0) sql1: EXPAND SELECT id, username, attribute, value, op FROM radcheck WHERE username = '%{SQL-User-Name}' ORDER BY id
(0) sql1:    --> SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'test' ORDER BY id
(0) sql1: Executing select query: SELECT id, username, attribute, value, op FROM radcheck WHERE username = 'test' ORDER BY id
(0) sql1: User found in radcheck table
(0) sql1: Conditional check items matched, merging assignment check items
(0) sql1:   Cleartext-Password := "test"
(0) sql1: EXPAND SELECT id, username, attribute, value, op FROM radreply WHERE username = '%{SQL-User-Name}' ORDER BY id
(0) sql1:    --> SELECT id, username, attribute, value, op FROM radreply WHERE username = 'test' ORDER BY id
(0) sql1: Executing select query: SELECT id, username, attribute, value, op FROM radreply WHERE username = 'test' ORDER BY id
rlm_sql (sql1): Reserved connection (2)
rlm_sql (sql1): Released connection (2)
(0) sql1: EXPAND SELECT groupname FROM radusergroup WHERE username = '%{SQL-User-Name}' ORDER BY priority
(0) sql1:    --> SELECT groupname FROM radusergroup WHERE username = 'test' ORDER BY priority
(0) sql1: Executing select query: SELECT groupname FROM radusergroup WHERE username = 'test' ORDER BY priority
(0) sql1: User not found in any groups
rlm_sql (sql1): Released connection (1)
(0)         [sql1] = ok
(0)       } # redundant sql = ok
(0)       if (notfound || noop) {
(0)       if (notfound || noop)  -> FALSE
(0)     } # if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept"))  = ok

          I had a 'test' user set up :

          e1be4832-76c8-4166-a0d5-88a960ed621c-image.png

          With

          files

          in place,
          your

          if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept"))

          yields a "FALSE, so the 'sql' block isn't executed.

          (that what I make of it).

          No "help me" PM's please. Use the forum, the community will thank you.

            This is correct because it finds the "test" user in the files backend.
            It checks files, sql and ldap backends sequentially.

              I did not (do not) have a 'test' user set up in the pfSense GUI - only in the 'radcheck' MYSQL table.

              Done on purpose, to see if the auth would fall through to 'radcheck testing' if no result was found in the 'files' (pfSense GUI).

                @gertjan in this case it should bypass files backend,
                my test (raduser1 in ldap backend, test1 user in files backend) with this patch:

                  @viktor_g :

                  Wait : your logs handle a 'files' and/or 'ldap'.
                  I'm using 'files' and 'sql1' (using the table 'radcheck' etc).

                  @AYSMAN didn't mention 'ldap'.

                    @gertjan Yes, but it uses the same logic (see /usr/local/etc/raddb/sites-enabled/default)

                    files + ldap:

                    if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept")) {
                        ### sql DISABLED ###
        if (true) {                     
          redundant {
          ldap
          # this line adds ldap2 when activated
         ### ldap2 disabled ###
        }
    if (notfound || noop) {
          reject
    }
 }
}

                    files + sql:

                    if ((notfound || noop) && ("%{%{Control:Auth-Type}:-No-Accept}" != "Accept")) {
         redundant sql {
                sql1
                ### sql2 DISABLED ###
        }
        if (notfound || noop) {
                        ### ldap ###
                        if (notfound || noop) {
                                reject
                       }
        }
 }

                        @viktor_g @Gertjan Since all of my previous set up using earlier version of the freeradius package is working with no errors. Can this be considered a valid bug for freeradius package version 0.15.7_27?

                            I confirm.
                            I was doing stupid things .... the correction proposed works very well.
                            @viktor_g : 👍
