Authentication fails when username contains specific characters.
Hi dear list. I'm sorry my English is not good. Authentication fails when the username contains the next 23 characters. (like Andy1 and Burt1) 23 chars -> !#$%&()*+,;<=>?[]^`{|}~ However, the authentication not fail when the password contains that 23 characters. (like Eddy) What do I need to do to solve the problem of Andy1 and Burt1 ? I read debug output and tried Andy2 and Burt2. (Enter equals sign and ASCII code in Hex (e.g. '=2B' for '+')) I found out that it will succeed in authentication, but is there any other solution ? Do I have to do this conversion each time I add a user ? I attached .bash_history and all files that may be useful. I think that the location of radtest in .bash_history is strange because of the execution of radtest from another teraterm window. The version is as follows.

What's happening is that the server is protecting you from SQL injection attacks. See: /mods-config/sql/main/mysql/queries.conf And the "safe_characters" configuration option. You can list more characters there, but your users will then be able to "own" your SQL database.
However, the authentication not fail when the password contains that 23 characters. (like Eddy) What do I need to do to solve the problem of Andy1 and Burt1 ?
Don't use special characters in user names.
I read debug output and tried Andy2 and Burt2. (Enter equals sign and ASCII code in Hex (e.g. '=2B' for '+')) I found out that it will succeed in authentication, but is there any other solution ? Do I have to do this conversion each time I add a user ?
I attached .bash_history and all files that may be useful.
Don't do that. We document the information we need. You get told what information we need when you join the mailing list. Alan DeKok.

Don't use special characters in user names.
I understood the following two points now. ・using special characters in user names cause SQL injection attacks. ・I must not use special characters in user names. By the way, Is "using special characters in passwords" danger against SQL injection attacks? (e.g. Eddy) You do not mention about the "using special characters in passwords". +----+----------+--------------------+----+-------------------------------+ | id | username | attribute | op | value | +----+----------+--------------------+----+-------------------------------+ | 6 | Eddy | Cleartext-Password | := | !#$%&()*+,-./:;<=>?@[]^_`{|}~ | +----+----------+--------------------+----+-------------------------------+

I am sorry. I do not understand what you are trying to say. I think that I have already joined the mailing list. Could it be that you are saying about that files which I attached? If so, I will be careful from now on.

That is data being *read* from SQL. So there is no possibility for injection attacks.
Don't do that. We document the information we need. You get told what information we need when you join the mailing list.

When you join the mailing list, you get an email. That email tells you what information you should include in posts to the list. Alan DeKok.
