You don't need to do anything to AD to allow an LDAP client to connect. You need to bind (authenticate) to LDAP to be able to browse it; you need to put in your full DN in JXplorer as part of the credentials, and of course your password. Without knowing what you've tried so far, I can't give you much more direction.
Corticosteroid injections usually contain 1 of the 3 most commonly used types of steroid (methylprednisolone (depo-medrol), triamcinolone (kenalog), or betamethasone (celestone) mixed with one or both numbing medications Lidocaine and Marcaine.
The most common one is Lovenox, but some people can't take Lovenox. I use one called Arixtra, when I need it. Both Lovenox and Arixtra are shots that you give yourself at home. Arixtra is a once-a-day injection; I'm not sure if Lovenox is given once a day or twice a day. A doctor or nurse can show you how to give yourself the shots. The injection will make a blue spot under your skin that looks like a bruise, but it is not painful.
