Регистрация нескольких пользователей с одного устройства на сервере ejabberd?

Question

Я работаю над smack chat library на сервере ejabberd. После конфигурации ejabberd я могу зарегистрировать пользователей с нескольких устройств одновременно и войти в систему несколькими пользователями, и пользователи могут правильно общаться, но проблема в том, что, когда я регистрирую несколько пользователей с одного и того же мобильного устройства быстро. он получает сообщение об ошибке, как:

org.jivesoftware.smack.sasl.SASLErrorException: SASLError using DIGEST-MD5: not-authorized 

и ejabberd.log файл я нашел:

<error code='500' type='wait'><resource-constraint xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/><text xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'>Users are not allowed to register accounts so quickly</text></error> 

Но когда я буду регистрировать пользователей из того же устройства через некоторое время он работает нормально. Я ищу в Интернете много, но я не мог найти подходящее решение, поэтому, пожалуйста, дайте мне соответствующее решение и есть ли способ сократить время регистрации пользователя с одного устройства. Мой ejabberd.yml файл:

### 
###'   ejabberd configuration file 
### 
### 

### The parameters used in this configuration file are explained in more detail 
### in the ejabberd Installation and Operation Guide. 
### Please consult the Guide in case of doubts, it is included with 
### your copy of ejabberd, and is also available online at 
### http://www.process-one.net/en/ejabberd/docs/ 

### The configuration file is written in YAML. 
### Refer to http://en.wikipedia.org/wiki/YAML for the brief description. 
### However, ejabberd treats different literals as different types: 
### 
### - unquoted or single-quoted strings. They are called "atoms". 
### Example: dog, 'Jupiter', '3.14159', YELLOW 
### 
### - numeric literals. Example: 3, -45.0, .0 
### 
### - quoted or folded strings. 
### Examples of quoted string: "Lizzard", "orange". 
### Example of folded string: 
### > Art thou not Romeo, 
###  and a Montague?

###' LOGGING 

## 
## loglevel: Verbosity of log files generated by ejabberd. 
## 0: No ejabberd log at all (not recommended) 
## 1: Critical 
## 2: Error 
## 3: Warning 
## 4: Info 
## 5: Debug 
## 
loglevel: 5 

## 
## rotation: Describe how to rotate logs. Either size and/or date can trigger 
## log rotation. Setting count to N keeps N rotated logs. Setting count to 0 
## does not disable rotation, it instead rotates the file and keeps no previous 
## versions around. Setting size to X rotate log when it reaches X bytes. 
## To disable rotation set the size to 0 and the date to "" 
## Date syntax is taken from the syntax newsyslog uses in newsyslog.conf. 
## Some examples: 
## $D0  rotate every night at midnight 
## $D23 rotate every day at 23:00 hr 
## $W0D23 rotate every week on Sunday at 23:00 hr 
## $W5D16 rotate every week on Friday at 16:00 hr 
## $M1D0 rotate on the first day of every month at midnight 
## $M5D6 rotate on every 5th day of the month at 6:00 hr 
## 
log_rotate_size: 10485760 
log_rotate_date: "" 
log_rotate_count: 1 

## 
## overload protection: If you want to limit the number of messages per second 
## allowed from error_logger, which is a good idea if you want to avoid a flood 
## of messages when system is overloaded, you can set a limit. 
## 100 is ejabberd's default. 
log_rate_limit: 100 

## 
## watchdog_admins: Only useful for developers: if an ejabberd process 
## consumes a lot of memory, send live notifications to these XMPP 
## accounts. 
## 
## watchdog_admins: 
## - "admin@TT_CPU_076" 

###. =============== 
###' NODE PARAMETERS 

## 
## net_ticktime: Specifies net_kernel tick time in seconds. This options must have 
## identical value on all nodes, and in most cases shouldn't be changed at all from 
## default value. 
## 
## net_ticktime: 60 

###. ================ 
###' SERVED HOSTNAMES 

## 
## hosts: Domains served by ejabberd. 
## You can define one or several, for example: 
## hosts: 
## - "example.net" 
## - "example.com" 
## - "example.org" 
## 
hosts: 
    - "TT_CPU_076" 

## 
## route_subdomains: Delegate subdomains to other XMPP servers. 
## For example, if this ejabberd serves example.org and you want 
## to allow communication with an XMPP server called im.example.org. 
## 
## route_subdomains: s2s

Answer 1

Посмотрите на registration_timeout тег в вашем ejabberd.yml файле & установите значение бесконечность.

Ex:

## By default the frequency of account registrations from the same IP 
## is limited to 1 account every 10 minutes. To disable, specify: infinity 

registration_timeout: infinity 

Вы должны быть в состоянии зарегистрировать более одного пользователя с того же самого устройства. Хотя предлагается отключить In-band регистрация по соображениям безопасности.
