Also having FTP authentication issues.

    I know there was a recently opened thread about this, but it did not seem to cover my problem, and I didn't want to hijack someones thread. I also receive a 530 Error when trying to connect via FTP using an account I created in ISPConfig 3.

    MySQL server is running properly and FTPd seems to be connecting to it properly (no errors generated).

    So, I have a client named "remarx" with an ftp account "ftp" ... so the username is "remarx_ftp" - still unable to login with it. Verified password and database entry. All look fine.

    Syslog only says:
    Code:
    Mar 24 06:39:50 dedi144 pure-ftpd: ([email protected]) [INFO] New connection from 24.129.83.69
    Mar 24 06:39:50 dedi144 pure-ftpd: ([email protected]) [WARNING] Authentication failed for user [remarx_ftp]
    Mar 24 06:39:54 dedi144 pure-ftpd: ([email protected]) [INFO] Logout.
    pureftpd.log is empty. I've turned on verbose logging to no avail. pureftpd.log is still empty. I've also (just to ease my own mind) verified the SQL statements and settings in pureftpd-mysql.conf and all look good.

    So, I'm at a loss with it. Any ideas?

    The problem that you have can also be caused by failing DNS lookups. Please disable dns resolving by settimg:

    DontResolve yes

    in the pure-ftpd.conf and then restart pure-ftpd.

    This was already done in the pure-ftpd.conf file when the fiasco started. Here is my pure-ftpd.conf

    Just an update. I enabled mysql logging in my.cnf and I can see pure-ftpd running the querys:
    Code:
    100324 19:57:14	      2 Connect     [email protected] on dbispconfig
    		      2 Query       set autocommit=0
    		      2 Query       SELECT password FROM ftp_user WHERE active = 'y' AND server_id = '1' AND username="remarx_ftp"
    		      2 Query       SELECT uid FROM ftp_user WHERE active = 'y' AND server_id = '1' AND username="remarx_ftp"
    		      2 Query       SELECT gid FROM ftp_user WHERE active = 'y' AND server_id = '1' AND username="remarx_ftp"
    		      2 Query       SELECT dir FROM ftp_user WHERE active = 'y' AND server_id = '1' AND username="remarx_ftp"
    		      2 Query       COMMIT
    		      2 Quit   
    I ran them in mysql as the ispconfig user and they produce the correct output:
    Code:
    [[email protected] ~]# mysql -u ispconfig -p
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or \g.

    So it would seem pure-ftpd is indeed using MySQL properly. Still no luck logging in though.

    The only thing has struck me as strange is the MinUID setting in /etc/pure-ftpd/pure-ftpd.conf - It is set to 500 and the UID on the FTP account is "web1" in the database (a nonexistent system user)

    try looking at /var/log/message

    I think by default pureftp logs into there.

    Yes, I can see the same messages in Monitor > View System-Log in ISPConfig. Nothing that really detailed the error I was having (mentioned above).

    What is stranger, is I switched the MYSQLEncrypt setting to 'cleartext' for testing and I still couldn't get any FTP-users authenticated using MySQL (after making the password cleartext in the database, of course). So, I changed it back to 'crypt' and recreated the FTP user, and logged in successfully..Go figure.

    Thanks for all the helpful hints. You are appreciated.
