I'm setting up an ejabberd server on an Ubuntu LTS 12.04. The community help wiki says I just need to:

1. Install the package
2. Edit the hosts configuration in ejabberd.cfg
3. Update the admin user's definition
4. Restart the server
5. Register the admin user from the command line

It's that last step that doesn't work. Here's what I get:

$ sudo ejabberdctl register ejabberd semperubisubsubi.org <password>
Can't register user [email protected] at node '[email protected]': not_allowed

There are a bunch of Google hits for "ejabber register not_allowed". I've spent about four or five hours reading them all. I still can't figure this out. I could really use some help.

I know most of the posts talk about making sure you have agreement between your hostname, your hosts definition, and your node name. The Ubuntu init scripts are setup to use /etc/defaults/ejabberd to override some of the settings via environment variables. The only thing I have in there is this line:

[email protected]

Which corresponds to my hostname:

$ hostname
semperubisububi.org
$ hostname -f
localhost
$ hostname -s
semperubisububi

I think that hostname -f is due to adding my FQDN to my /etc/hosts:

127.0.0.1  localhost susu semperubisububi.org

Oh, I also found a post that says there's a tight bind between the hostname of your machine and the ejabberd configuration. I think while I was wrestling with this setup, I got that mucked up. The post said to rm /var/lib/ejabberd/* and restart. I wasn't actually able to get the server running properly until I did that. I know the server is running properly:

 sudo ejabberdctl status
The node '[email protected]' is started with status: started
ejabberd 2.1.10 is running in that node

And I can see the processes running:

$ ps -ef | grep eja[b]
ejabberd  1152     1  0 13:19 ?        00:00:00 /usr/lib/erlang/erts-5.8.5/bin/beam -K false -P 250000 -- -root /usr/lib/erlang -progname erl -- -home /var/lib/ejabberd -- -name [email protected] -pa /usr/lib/ejabberd/ebin -s ejabberd -kernel inetrc "/etc/ejabberd/inetrc" -ejabberd config "/etc/ejabberd/ejabberd.cfg" log_path "/var/log/ejabberd/ejaberd.log" erlang_log_path "/var/log/ejabberd/erlang.log" -sasl sasl_error_logger false -mnesia dir "/var/lib/ejabberd" -smp disable -noshell -noshell -noinput

can it be that you mistyped semperubisubsubi.org in your config file?
As an alternative, have you tried registering a user with the localhost hostname?

I was getting a similar error, but I am using ejabberd 14.07-4+deb8u1 on raspbian. It is using a yml configuration file.

I managed to get past the set giving the above problem by not removing the 'localhost' in the 'acl' setting for admin users. Looks like it's needed for 'ejabberdcfg'. I wanted to get rid of the 'localhost' reference.

' ACCESS CONTROL LISTS

acl:

The 'admin' ACL grants administrative privileges to XMPP accounts.

You can put here as many accounts as you want.

admin:
user:
- "": "localhost"

I faced similar issue, add a entry in ejabberd.cfg like below
{acl, admin, {user, "admin", "example.com"}}

then run command
ejabberdctl register admin example.com password
User [email protected] successfully registered

I solved it as follows on Ubuntu 16.04:

In /etc/ejabberd/ejabberd.yml, make sure that your domain is present under hosts :

hosts:
  - "localhost"
  - "semperubisububi.org"

To my surprise, this is not noted in the installation guide, but it did not work for me until adding the host here.

@g0ldstrike thanks . That was it

It worked. Thanks man

i do like this :
-purge all package
apt-get purge ejabberd ejabberd-)
-config hostname in /etc/hostname : this hostname will be used in ejabberdctl script
-reinstall
apt-get install ejabberd ejabberd-
-config /etc/hosts, add your hostname, ex : xmppchat.org
-config ejabberd serving hosts :
hosts :
- "localhost"
- "xmppchat.org"
-then just register user :
ejabberdctl register admin xmppchat.org 123abc

[SOLVED _SEE BELOW]

I'm having the same problem with a Raspberry Pi 3 - Raspbian Stretch.
I've updated /etc/ejabberd/ejabberd.yml - actually my hostname was already in there but "localhost" wasn't, so added it for the hell of it.
I then ran the command as per above,

$ sudo ejabberdctl register ejabberd semperubisubsubi.org

. I run:

$ sudo ejabberdctl register ejabberd <my host name.com> <password>

but I get:

Error: cannot_register

I've also tried the above as root i.e.,:

sudo su.

Please can someone clarify what the correct command is to register an admin user so that I can login to the web admin?

Thanks...

Got it....I'm running ejabberd on a Rasberry Pi 3 with a FreedomBox software install - https://wiki.debian.org/FreedomBox - and the admin for ejabberd must be setup by FreedomBox to be the FreedomBox admin, domain and password. To make sure I was using the right domain I ran the following command in the commandlline:

hostname -s

my login is:
Username: [FreedoBox admin name]@[domain]
Password: [FreedomBox admin password]
