missing dependene File Logger

On line 133 in og_ldap.module function flog_it is being used, this module ( File logger ) is not assigned in array depenencies[] in og_ldap.info

I would use watchdog instead.

Like this:
watchdog('og_ldap', 'Added new OG group from LDAP, groupname: @groupname', array('@groupname' => $group), WATCHDOG_NOTICE);
