Install on RedHat - accounts get created, but login not possible

Hello,

"runs out-of-the-box under every Linux/x86 distribution" is what I have read about the ejabberd-linux-....-.bin. So I did that - installed it through that .bin file, and started it with /opt/ejabberd-1.0.0/bin/start . Text browser opened. Can open the admin interface from another machine inside the browser as well.

Next thing - I used Trillian to create a new account user@domain (anonymized for the forum - of course I use a valid internal subdomain that's pingable from all clients). No problem - account appears in admin interface. But whenever I try to connect, I get:

[18:55] *** Creating connection "user@domain/Trillian"
[18:57] *** Connection to server lost.
[18:57] *** Disconnected from server.
[18:57] *** Reconnecting to domain, attempt 0...
[18:57] *** Creating connection "user@domain/Trillian"
[18:57] *** Connect: Unable to contact domain to get a connection at all

So I took a Linux box, fired up gaim, created an account user2@domain. Account was successfully created (so there IS a connection to the server). But when I try to use that account, I get "Fehler beim Lesen" ("Error while reading").

One of my ideas was ACLs... but while I find {access,register,[{allow,all}]}, I found none about connecting.

The ejabberd log file tells me:

** Reason for termination =
** {badarg,[{ets,lookup,[crypto_server_table,port]},
            {crypto,control,2},
            {cyrsasl_digest,response,6},
            {cyrsasl_digest,mech_step,2},
            {cyrsasl,server_step,2},
            {ejabberd_c2s,wait_for_sasl_response,2},
            {gen_fsm,handle_msg,7},
            {proc_lib,init_p,5}]}

I put in a ssl.pem file, I changed the config settings to point there as well (even though those lines are commented out in the config file), to no avail.

Any hints on how I could proceed to get this running would be greatly appreciated.
