Admin config screen blank when login

Windows Server 2012R2
MantisBT 2.25.2
Not sure where to start troubleshooting this. Updated to v2.25.2 and copied over all of the plugins we installed and made appropriate config file changes. Everything seems to work except when I go into the Management screen and it asks me to verify my password. I enter that and it seems to accept it, but then goes to a blank gray screen. The layout doesn't match the original color scheme either. Where should I start to look? Perhaps I missed some file copy or forgot to edit something in the config.
Note: I copied over the previous version user config files, I did not use the new version. So if there are extra settings in the user config file then i will need to know what those are.
Also, what is the difference between a $t_ and $p_ variables please?

Guess there's light forum traffic during the holidays. :-(
I'm thinking it has something to do with the ADlogin plugin not authenticating properly but that's just a guess. It seems like it is not reading the css or something but I just don't know where to start looking.

so if you deactivate that plugin all works as expected?

I can't get in to do anything admin related. If I remove the adLogin plugin directory the entire site fails with this error:
APPLICATION ERROR #1406
Cannot initiate StartTLS on LDAP server.
Please use the "Back" button in your web browser to return to the previous page. There you can correct whatever problems were identified in this error or select another action. You can also click an option from the menu bar to go directly to a new section.
Detailed error information
Full path: C:\MantisBT2252\core\ldap_api.php
Line number: 127
The plugin itself is literally just this code:
Code: Select all
<?php
class adLoginPlugin extends MantisPlugin {
function register() {
$this->name = 'adLogin';
$this->description = 'Automated login within AD';
$this->version = '1.01';
$this->requires = array('MantisCore' => '2.0.0',); # 1.2.0
$this->author = 'Cas Nuy';
$this->contact = 'Cas-at-nuy.info';
$this->url = 'http://www.nuy.info';
}
function init() {
plugin_event_hook( 'EVENT_CORE_READY', 'login_ad' );
}
function login_ad() {
if ( isset($_SERVER['AUTH_USER'])) {
$temp = explode('\\', $_SERVER['AUTH_USER']);
if ($temp[1] == "") {
$name = $temp[0];
} else {
$name = $temp[1];
}
$ok=auth_attempt_script_login( $name );
}
}
}
I just saw that the referenced file (ldap_api.php) is about 2k bigger in the new version of Mantis than the old one, so obviously a fair amount of changes have been done there. Wonder if there is anything I can tweak in the adLogin plugin to get it to work again?

Also, it should be noted that with the plugin directory there the main screen of Mantis works properly and I can do everything normally like I used to. It only fails when I click the Maintenance button and enter my password.

hangon, this plugin does not touch the LDAP server at all. This only works on Windows, check the readme with that plugin. But do not use login method LDAP. What other plugins have you enabled now?

using phpmyadmin, you can simply disable plugins.
Open up table mantis_plugin_table and change value of field "enabled" to 0.
Do not change plugin "MantisCoreFormatting"

Note that these all worked just fine in Mantis v2.24.3 since I simply copied them into the new version plugins folder:
Code: Select all
C:\MantisBT2252\plugins>dir

When I disable that plugin by editing the table and go to the homepage of the Mantis install I still get the same error as before (but if I put it back in it works fine until I click the Manage button):

What is your login method?

Active Directory since it is installed on a local server in the network.
EDIT: Windows Authentication in IIS with all other methods disabled on the site.

Forgot to say that I also updated PHP from 5.6 to 7.4 and copied over the php.ini file from the old version, then verified that there were no version-specific or directory-specific issues in it. I remember reading that PHP 7 had some kind of breaking issue a while back, but assume that has all been fixed in Mantis by now.

GOT IT FIGURED OUT!
It was using STARTTLS for the LDAP server (carried in from the default config settings, thus I missed it) which is not configured for that. I turned that option off in the config file and then it logged me in and went to the "checking installation" screen and everything was good *except* for this:
Code: Select all
Plugins
'HTMLMail': Missing Plugin
The plugin is installed in the Mantis database, but could not be loaded.
Remove the Plugin or reinstall its source code.
So would I disable that plugin and then try to reinstall it from the Manage screen?
EDIT: not sure where I got that plugin but I deleted it and everything seems to be working fine now. Thanks for your help cas!

I've been comparing the code changes in the ldap_api.php file and starting around line 100 there is a bunch of new code that starts checking TLS protocol stuff that it didn't do before. That is what killed me since the defaults in the default_config.php file had those options enabled but our setup wasn't using that.
Would have been nice to have mentioned the TLS protocol code changes for LDAP in the release notes.

It looks like your mantis Login Method was set to LDAP which should not be the case when using the adLogin plugin.......
Good to hear all is sorted now.
