I am finishing my mail server config and just trying to get the mysql login working - it fails to connect and thorws the following error

Mar 21 21:58:21 mail0 authdaemond: failed to connect to mysql server (server=localhost, userid=courier): Can't connect to local MySQL server through socket '/tmp/mysql.sock.' (2) Mar 21 21:58:21 mail0 couriertcpd: LOGIN FAILED, user=tom@xxx.xxx, ip=[::ffff:192.168.10.200] Mar 21 21:58:21 mail0 couriertcpd: authentication error: Input/output error

The socket exists

# ll /tmp/mysql.sock srwxrwxrwx 1 mysql mysql 0 Mar 21 21:53 /tmp/mysql.sock

and mysql seems to be working fine using the same credentials

# mysql -S /tmp/mysql.sock -u courier -pxxxxxx Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 7 to server version: 5.0.22

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

some bits from the my.cnf

[client] port = 3306 socket = /tmp/mysql.sock

[mysqld] port = 3306 datadir = /var/lib/mysql socket = /tmp/mysql.sock

any ideas as i am a bit stumped

in the end i resolved this by removing the use of sockets from authdaemond and used tcp connections instead
