cPanel login redirect loop

[Justin Emmons]

I am unable to login on my CPanel. I get a successful login message, and then it loops back to the login page each time. Everything was fine before I rebuilt to Apache 2.4.

Hello,

Do you notice any error messages in /usr/local/cpanel/logs/error_log or /usr/local/cpanel/logs/login_log when this happens?

Thank you.

/usr/local/cpanel/logs/login_log shows the following:

"POST /login/?login_only=1 HTTP/1.1" FAILED LOGIN whostmgrd: login attempt to whm by a non-reseller/root
DEFERRED LOGIN cpaneld: switchuser: uid or gid passed user switch is less than 99

Hello,

The error message suggests the UID or GID for one of your users is possibly below "99". Could you search the /etc/passwd and /etc/shadow files to see if the user you are logging in as, or any user for that matter, utilizes a low numbered UID/GID? Here's the commands to use:

grep $username /etc/passwd
grep $username /etc/shadow

Or, view the full /etc/passwd and /etc/shadow files with the "cat" command to find the offending account.

Thank you.

$username:x:501:48::/home/$username:/bin/bash

The GID needs to be above 99? Does that mean it would have access to anything set to or below 99?

Hello,

The "48" GID alone does not grant root privileges to a user. You can review the following FAQ entry for additional information about how cPanel assigns UID and GID numbers:

Which UID and GID values are assigned to accounts

Thank you.
