Tutorials – Servers > Telnet as a Diagnostic Aid

I don’t know about you, but I can use a reefresher now and again for things like surfing with Telnet to determine if 301 re-directs work…

In a nutshell, you’ll want something like this:

telnet eastvalley.freedomblogging.com 80[cr]
Trying 69.25.233.100…
Connected to eastvalley.freedomblogging.com.
Escape character is ‘^]’.
HEAD / HTTP/1.1[cr]
Host: eastvalley.freedomblogging.com[cr]
[cr]

Note: italic items are sent by the server, whilst non-italic items are typed. Also NOTE the double carriage return ([cr]) at the end.

Authenticate Apache 2 using Mac OS X Open Directory

macosxhints.com – Authenticate Apache 2 using Mac OS X Open Directory

Change this:

cn=user1,dn=example,dn=com

to this:

uid=user1,dn=example,dn=com

so it looks like this:

AuthType Basic
AuthName "Testing of LDAP auth"
AuthBasicProvider ldap
AuthzLDAPAuthoritative on
AuthLDAPBindDN uid=testaccount1,cn=users,dc=geo,dc=vuw,dc=ac,dc=nz
AuthLDAPBindPassword [plaintext password for user 'testaccount1']
AuthLDAPURL ldap://server1.geo.vuw.ac.nz/dc=geo,dc=vuw,dc=ac,dc=nz
require valid-user

Clear as mud? 😉
