Update: It seems slapd (openldap) was to blaim.
as you can see from the stacktraces http://foo.mu/mongo.out (root) http://foo.mu/mongo2.out (non-root) they both try port 389 (ldap) first. As non-root, it'll fall back on port #53. The weird thing is: [EMAIL PROTECTED]:~# grep hosts /etc/nsswitch.conf hosts: dns ldap So I can't get this to add up. Suggestions?
