Misleading docs about customer user authentication over LDAP

[svenoe]

From: RotherOSS/otobo#953 (comment)

I was working on setting up customer authentication over LDAP (specifically Active Directory) on a clean installation of Otobo. Following the admin docs about Customer User Backend I was able to get a list of customer users after configuring:

$Self->{CustomerUser} = {
        Name => 'LDAP Backend',
        Module => 'Kernel::System::CustomerUser::LDAP',
        Params => {
        ...
}

I was convinced that was is all that is needed for customer user to authenticate through customer frontend. After hours of failing to realize what is the problem I got the hang of it. Frontend was using DB authentication, since I didn't change Customer::AuthModule settings. After realizing this I got it working in no time.

This configuration is not mentioned at all in admin docs. If this is by design then I think it should be added to admin docs. I would gladly make a pull request to doc-otobo-admin repo.

Hi, here, too,

it's definitely not intended. I quickly asked around and we would be happy about a pull request for this.

Thanks, Sven :)
