mysql plugin "couldnt connect to any host"

[twebster at daksoft.com]

I found the solution to my problem.  Most examples in the cyrus-sasl
mailing list using the following imapd.conf

pwcheck_method: auxprop
auxprop_plugin: mysql
mysql_user: username
mysql_passwd: password
mysql_hostnames: localhost
mysql_database: horde
mysql_statement: select password from accounts where username = '%u'
mysql_verbose: true

but this did not work for me:   I used the following

pwcheck_method: auxprop
auxprop_plugin: mysql
sasl_mysql_user: username
sasl_mysql_passwd: password
sasl_mysql_hostnames: localhost
sasl_mysql_database: horde
sasl_mysql_statement: select password from accounts where username = '%u'
sasl_mysql_verbose: true

Working now,
