I wonder if I'm the only one who finds it ironic that LDAP, of all the Internet protocols the one most directly aimed at fixing the problem of discoverability, is, itself, undiscoverable:
I happen to know the hostname of my company's LDAP server, so I only need to figure out 7 more settings before I can, you know, find out my colleagues' email addresses.
Uploading this screenshot was an ordeal, by the way. Mac OS has screen-capture hotkeys (Command-Alt-Shift-3 or something absurd like that), but it can't capture just one window. It also comes with a separate screen-capture program (Grab)... which unhelpfully saves your screenshots in TIFF format. (There is no way to configure this.) And Mac OS does not come with any basic image-hacking utility like Paint. Great style, awful usability.
While I'm on a roll:
$ nslookup > help The 'help' command is not yet implemented.
Oh, thank you. Thank you so much.
Update: Some great Mac OS screenshot tips are in the comments. (Thank you!)
