Re: Problem with email as username

["Jorge Bastos" <mysql.jorge@xxxxxxxxxx>]

Hi nicolas,

I've added -d for its start, but i didn't saw nothing relevant.

the test with:

testsaslauthd -f /var/spool/postfix/var/run/saslauthd -r -s smtp -u <user> -p <pass>

always return no auth even with a normal username.

How can i debug more this?

Hi,

I've been using sasl for 2 years, with standard usernames, but i'd like to use usernames in the format of emails like:

 

jorge@xxxxxxxxxx

 

but, when i insert this it doesn't authenticate, i went to mysql logs and checked that:

 

---

55 Query       select password from smtp_auth_users where username='jorge'
and status='true'

---

 

It makes everything including the "@" away.

 

Any reason for this?

I posted a similar problem some time ago on this list. Here's my outcome:

Relevant stuff in the pam_mysql README:


verbose (0)

    If set to 1, produces logs with detailed messages that describes what
    PAM-MySQL is doing. May be useful for debugging.


crypt (plain)

    The method to encrypt the user's password:

       0 (or "plain") = No encryption.  Passwords stored in plaintext.
                        HIGHLY DISCOURAGED.

       1 (or "Y")     = Use crypt(3) function.

       2 (or "mysql") = Use MySQL PASSWORD() function. It is possible
                        that the encryption function used by PAM-MySQL
                        is different from that of the MySQL server, as
                        PAM-MySQL uses the function defined in MySQL's
                        C-client API instead of using PASSWORD() SQL
function
                        in the query.
                       
       3 (or "md5")   = Use plain hex MD5



So I modified /etc/pam.d/smtp to use verbose=1 and, finally, crypt=2,
since this seemed to be the problem.

auth required pam_mysql.so user=<user@address> passwd=<pass>
host=127.0.0.1 db=mail table=postfix_users usercolumn=email
passwdcolumn=clear crypt=2 verbose=1

account sufficient pam_mysql.so user=<user@address> passwd=<pass>
host=127.0.0.1 db=mail table=postfix_users usercolumn=email
passwdcolumn=clear crypt=2 verbose=1

So that would be

# /usr/sbin/saslauthd -d -a pam &
[1] 3654
saslauthd[3654] :main            : num_procs  : 5
igloo:/home/nicolas# saslauthd[3654] :main            : mech_option: NULL
saslauthd[3654] :main            : run_path   : /var/run/saslauthd
saslauthd[3654] :main            : auth_mech  : pam
saslauthd[3654] :ipc_init        : using accept lock file:
/var/run/saslauthd/mux.accept
saslauthd[3654] :detach_tty      : master pid is: 0
saslauthd[3654] :ipc_init        : listening on socket:
/var/run/saslauthd/mux
saslauthd[3654] :main            : using process model

saslauthd[3654] :have_baby       : forked child: 3657
saslauthd[3654] :have_baby       : forked child: 3658

... and there you go # testsaslauthd -s smtp -u <user@address> -p <pass> saslauthd[3756] :rel_accept_lock : released accept lock saslauthd[3757] :get_accept_lock : acquired accept lock saslauthd[3756] :do_auth : auth success: [user=<user@address>] [service=smtp] [realm=] [mech=pam] saslauthd[3756] :do_request : response: OK 0: OK "Success."
