Topic on Project:Support desk

Osnard pointed me in the right direction. I disabled the Extension:LDAP_Authentication (for now) and can now use the account again.

Environment

• Mediawiki: 1.26.2
• PHP: 5.5.9-1ubuntu4.21 (apache2handler)
• MySQL: 5.5.54-0ubuntu0.14.04.1

I can no longer log in using WikiSysop.  (Error message: "Login error - Incorrect password entered. Please try again.")

When I try to reset the password, from the "Reset password" special page, I receive the error 'There is no user by the name "WikiSysop". Usernames are case sensitive. Check your spelling, or create a new account.'

And yet the user exists in the database and has been assigned to the proper groups:

mysql> select * from mw_user where user_name='WikiSysop'\G
*************************** 1. row ***************************
                 user_id: 1

I tried recreating the user but that didn't work either:

# php createAndPromote.php --bureaucrat --sysop WikiSysop mypassword

Anyone any idea what may be wrong?

On an unrelated note, you are using an old unsupported version which has security issues. Please upgrade to a supported version.

Could you provide a link to your wiki?

No, it's not accessible to the outside world.

Do you use Extension:LDAP_Authentication? Maybe the username is being normalized to lowercase. You could try creating a user "Wikisysop" (with lower case "s").

I had indeed tried to use that extension, but abandoned that little project for more urgent matters. When I comment out the settings in LocalSettings.php, the account works again.

Thanks, Osnard!
