[Solved] pure-ftpd issues - check pass; user unknown

I searched the forum before posting without being able to resolve.

I installed the server following the tutorial perfect server
When try to connect the response from filezilla is:

Code:

Status:          Connecting to 1.2.3.4:21...
Status:          Connection established, waiting for welcome message...
Status:          Initializing TLS...
Status:          TLS connection established.
Command:    USER *******
Response:     331 User ****** OK. Password required
Command:    PASS ***********
Response:     530 Login authentication failed
Error:            Critical error: Could not connect to server

/var/log/auth.log:

Code:

Apr 29 16:30:33 ded pure-ftpd: pam_unix(pure-ftpd:auth): check pass; user unknown
Apr 29 16:30:33 ded pure-ftpd: pam_unix(pure-ftpd:auth): authentication failure; logname= uid=0 euid=0 tty=pure-ftpd ruser=****** rhost= 

It's strange, is the first time that I have that issues.
Port range 40110:40210 and TLS are enabled, server is not behind NAT and I sure that ports are opens.
The user exists in the dbispconfig database, I also tried to delete and then recreate from ispconfig panel without success.
Anyone have any suggestions?

 

Hi, thanks for the reply.
Yes, I installed pure-ftpd-mysql and the ftp user is present on the dbispconfig.

 

Even without special symbols in password I can't log in.
Is it possible to increase the verbose log on pure-ftpd?

 

Thanks Till, it seems a problem connecting trhough loopback.

Code:

[ERROR] The SQL server seems to be down [Access denied for user 'ispconfig'@'127.0.0.1' (using password: YES)]

Changing to localhost all works.
Thanks again.
