I have configured vsftpd with the "text_userdb_names=YES" option, which is expected to put user and group names into the listing. The server is configured with nscd and ldap. The users are chrooted into a 'general root' directory, but that doesn't affect the result (not chrooting still fails).
The problem: obvious timeouts and unsuccessful resolving of 'group names'. The 'ls' output contains correct usernames but instead of a groupname there is a number.
