many problems: pam / hostname / ejabberctl crash

Hello,

I've been trying to install ejabberd with pam authentication. I've been chasing one error after another. I must say, this is a pain in the butt.

I compiled everyting as described here:
http://www.ejabberd.im/pam
and
http://www.ejabberd.im/tuto-install-ejabberd

What I want, is that only local system users can log on to this jabber server, nobody can create an account, and new system accounts can automatically log on to jabber server with systemusername@servername.tld ans system password. (TLS only)

I have finally managed to get the server running with the command:
su ejabberd -c "erl -pa /var/lib/ejabberd/ebin -sname ejabberd -s ejabberd -ejabberd config '\"/etc/ejabberd/ejabberd.cfg\"' log_path '\"/var/log/ejabberd.log\"' -detached -noshell"

When I try to connect to the server with kopete and use myusername@myservername.tld and my password:
I(<0.306.0>:ejabberd_c2s:417): ({tlssock,#Port<0.352>,#Port<0.356>}) Failed legacy authentication for myusername@myservername.tld/Kopete

is PAM even coming to play here?

if I type 'ejabberdctl' I get
{"init terminating in do_boot",{badarg,[{ets,match_object,[ejabberd_ctl_cmds,'_']},{ets,tab2list,1},{ejabberd_ctl,print_usage,0},{ejabberd_ctl,start,0},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

and if I type 'ejabberdctl myusername@myservername.tld' I get
RPC failed on the node 'myusername@servernam.tld': nodedown

=ERROR REPORT==== 17-Aug-2007::23:20:05 ===
** System NOT running to use fully qualified hostnames **
** Hostname myservername.tld is illegal **

incidentaly
hostname -s gives myservername and hostname -f gives myservername.tld

the sections of the config file that might be interesting are:

{registration_watchers, ["myusername@servernam.tld"]}.

% Only admins can send announcement messages:
{access, announce, [{allow, admin}]}.

% Only non-blocked users can use c2s connections:
{access, c2s, [{deny, blocked},
{allow, all}]}.

% Set shaper with name "normal" to limit traffic speed to 1000B/s
{shaper, normal, {maxrate, 1000}}.

% Set shaper with name "fast" to limit traffic speed to 50000B/s
{shaper, fast, {maxrate, 50000}}.

% For all users except admins used "normal" shaper
{access, c2s_shaper, [{none, admin},
{normal, all}]}.

% For all S2S connections used "fast" shaper
{access, s2s_shaper, [{fast, all}]}.

% Admins of this server are also admins of MUC service:
{access, muc_admin, [{allow, admin}]}.

% All users are allowed to use MUC service:
{access, muc, [{allow, all}]}.

% This rule allows access only for local users:
{access, local, [{allow, local}]}.

% Authentication method. If you want to use internal user base, then use
% this line:
%{auth_method, internal}.

% For LDAP authentication use these lines instead of above one:
%{auth_method, ldap}.
%{ldap_servers, ["localhost"]}. % List of LDAP servers
%{ldap_uidattr, "uid"}. % LDAP attribute that holds user ID
%{ldap_base, "dc=example,dc=com"}. % Search base of LDAP directory
%{ldap_rootdn, "dc=example,dc=com"}. % LDAP manager
%{ldap_password, "******"}. % Password to LDAP manager

% For authentication via external script use the following:
%{auth_method, external}.
%{extauth_program, "/path/to/authentication/script"}.

% For authentication via ODBC use the following:
%{auth_method, odbc}.
%{odbc_server, "DSN=ejabberd;UID=ejabberd;PWD=ejabberd"}.

%%% Add new auth method
{auth_method, [internal, pam]}.

%%% Default pam service "login" can be change
%{pam_service, "login"}.
%%% Default pam prompt "Password:" can be change
%{pam_prompt_pwd, "Password:"}.

% Host name:
{hosts, ["myservername.tld"]}.

and further at the bottom:

{mod_echo, [{host, "echo.myservername"}]},

everything else is as in the default.

thank you for any help,

aron

PS how exactly do I have to change the line
{5280, ejabberd_http, [http_poll, web_admin]},
to get http://localhost:5280 to work but not http://myservername.tld:5280
as in http://www.ejabberd.im/node/1674
