[imp] Log level and login/logout messages

[Luis Felipe Marzagao]

Hello:

I have $conf[log][priority] set to WARNING, but I still get login and 
logout messages in the log file:

May 28 21:01:51 mserver HORDE: [imp] Login success for reunioes (Horde 
user reunioes) [186.220.40.240] to {localhost:1143 [imap]} [pid 5056 on 
line 183 of "/var/www/horde/imp/lib/Auth.php"]

May 28 21:03:41 mserver HORDE: [horde] User lfbm [186.220.33.14] logged 
out of Horde [pid 5045 on line 118 of "/var/www/horde/login.php"]

Shouldn't those messages be logged only in levels like INFO or DEBUG?

Thanks!
Luis Felipe
