Ejabberd external auth with python is giving timeout error

I'm getting below error message in error.log of ejabberd when i try to authenticate through an external python script (Tried with java also).

External script is succesfully receiving inputs from ejabberd and processing it how it should. But it takes a long time to receive the input in external script , by that time ejabberd gets timedout.

                       {shutdown,5000},
                       {child_type,worker}]

External auth configuration in ejabberd.yml :

auth_method: external
extauth_program: "/usr/bin/python3 /home/ejabberd/external-auth.py"
extauth_pool_size: 1

I'm using ejabberd/ecs docker image. Copied python script inside the custom docker image created from ejabberd/ecs.

Any help much appreciated

Solution

  • I created a container from image ejabberd/ecs:latest

    Copied your three configuration lines, and the example script from the documentation, ejabberd complains at start:

    main_1  | sh: exec: line 0: /usr/bin/python3: not found
main_1  | 2023-03-20 17:02:10.958586+00:00 [error] Failed to start external authentication program '/usr/bin/python3 /home/ejabberd/external-auth.py'
main_1  | 2023-03-20 17:02:10.958801+00:00 [error] SUPERVISOR REPORT:

main_1  |                {id,extauth_pool_localhost_1},
main_1  |                {mfargs,{extauth,start_link,
main_1  |                                 [extauth_pool_localhost_1,
main_1  |                                  "/usr/bin/python3 /home/ejabberd/external-auth.py"]}},
main_1  |                {restart_type,permanent},
main_1  |                {significant,false},
main_1  |                {shutdown,5000},
main_1  |                {child_type,worker}]
main_1  | 
main_1  | sh: exec: line 0: /usr/bin/python3: not found

    So I add python3:

    apk add python3

    Now ejabberd starts correctly. When I try to login to an existing account, it logins correctly:
