# postfix stop > /usr/sbin/postconf: warning: read "ldap" configuration > "/etc/postfix-submission/ldap": Is a directory
I'm closing this bug, so that I can unblock the Postfix 3.3 release. The reporter has not provided configuration details for reproducing this. Based on a reverse code analysis starting with the warning message, I can only reproduce the warning message when main.cf or master.cf contain, after $name expansion, a parameter value of the form: ... maptype:/etc/postfix/ldap ... ... word:{... maptype:/etc/postfix/ldap ...} ... ... word:{... word:{... maptype:/etc/postfix/ldap ...} ...} ... and so on, recursively, where 'maptype' is a Postfix database type that uses a configuration file (examples: ldap, memcache, *sql) perhaps with a prefix of 'proxy:', and 'word' is a sequence that does not contain comma or whitespace.
