6 Creating an Initial Administrator
Before the web interface can be entered to perform administration tasks, an account with administrator rights is needed on your ejabberd deployment.

Instructions to create an initial administrator account:

1. Register an account on your ejabberd deployment. An account can be created in two ways:
1. Using the tool ejabberdctl (see section 7.2):

% ejabberdctl node@host register admin example.org password

2. Using In-Band Registration (see section 5.14): you can use a Jabber client to register an account.
2. Edit the configuration file to promote the account created in the previous step to an account with administrator rights. Note that if you want to add more administrators, a seperate acl entry is needed for each administrator.

{acl, admins, {user, "admin", "example.org"}}.
{access, configure, [{allow, admins}]}.

3. Restart ejabberd to load the new configuration.
4. Open the web interface (http://server:port/admin/) in your favourite browser. Make sure to enter the full JID as username (in this example: admin@example.org. The reason that you also need to enter the suffix, is because ejabberd's virtual hosting support.
