Authentication Failure (pam-auth pam_auth_pass : Authentication failure)

[pencilvania]

I have successfully installed ocserv on an Ubuntu 20.04 server using the provided install.sh script. However, I encountered an issue when attempting to create a user and log in. The server generates the following error message:

pam-auth pam_auth_pass : Authentication failure

This issue prevents users from authenticating and accessing the VPN server.

Steps to Reproduce:

Install ocserv on an Ubuntu 20.04 server using the install.sh script. Create a user account using panel. Attempt to log in with the newly created user account. Observe the "Authentication failure" error. Expected Behavior: I expected to be able to create a user account and log in to the ocserv VPN server without encountering authentication errors.

Additional Information:

Operating System: Ubuntu 20.04 Installation Method: install.sh script provided with ocserv-users-management. Any relevant logs or error messages should be included here for further diagnosis.

The authentication of panel and ocserv is plain. you try to use pam authentication method. the users will be store in file /etc/ocserv/ocpasswd and auth method is : auth="plain[passwd=/etc/ocserv/ocpasswd]"

try command below to create a test user in server: echo test\ntest\n | sudo ocpasswd -c /etc/ocserv/ocpasswd test
or try to create from pannel in http://YOUR_SERVER_IP in user tab

then try in client side to connect with command below: sudo openconnect -u test YOUR_IP_ADDRESS:OCSERV_PORT password is : test default oscerv port: 20443

If there is an error, please report the bug, so that I can fix it. After test remove user from panel or delete user from file /etc/ocserv/ocpasswd

@mmtaee I tested with commands , but I cannot login again

when I use anyconnect app I get pam authentication method

but when I using with command line it cannot pass Auth

This part is not Ocserv password. It is related to the password of the system administrator (sudo) .
