[Serusers] SER got error during the start due to MySQL connection 2

[ser at ipcb.net]

Hi all.

I have configured ProxySER for my test clients and connected they via 
SER, but... I can't configure SER - MySQL interoperability. I've read 
"SIP.edu Cookbook" by ProxySER afterward I made the changes into ser.cfg 
and db configuration. After SER startup I've got the next log:


Aug  2 19:21:21 fwd ser[11846]: Maxfwd module- initializing
Aug  2 19:21:21 fwd ser[11849]: new_connection(): Access denied for user 
'serro'@'localhost' (using password: YES)
Aug  2 19:21:21 fwd ser[11849]: db_init(): Could not create a connection
Aug  2 19:21:21 fwd ser[11849]: ERROR: auth_db_bind: unable to connect 
to the database

Aug  2 19:21:21 fwd ser[11849]: ERROR: open_uac_fifo: init_child failed
Aug  2 19:21:21 fwd ser[11849]: starting fifo server failed

I've had the next config:

Where I can dig for solving this trouble?

Thank you in advance.
