x.509 – RFC 5280 compliant certificate with x509 extensions

Be careful when posting here for the first time.

situation:
I have a request to link our printer / scanner to our Azure AD (so that users, etc. can be searched). I have enabled Azure AD Domain Services with LDAP enabled and that works. I've tested the LDAP search by creating a certificate with the x509 extensions in the Azure documentation, installing the LDAP certificate in AADDS and on my laptop, and successfully searching the domain. Without the certificate it will not work – so for safety's sake it seems to be okay.

Azure AD DS says:

Upload a .PFX file containing the certificate to be used for security
LDAP access to this managed domain

The requirements for the Azure AD DS-LDAP certificate can be found here:
https://docs.microsoft.com/de-de/azure/active-directory-domain-services/configure-ldaps:

Requirements for the secure LDAP certificate
Purchase a valid certificate according to the following guidelines before enabling secure LDAP. Errors occur when you try to enable secure LDAP for your managed domain with an invalid / incorrect certificate.

Trusted Issuer - The certificate must be issued by a trusted computer that connects to the managed domain through secure LDAP. This authority can be a public certification authority (CA) or enterprise CA that trust these computers.
Lifetime - The certificate must be valid for at least the next 3-6 months. Secure LDAP access to your managed domain is interrupted when the certificate expires.
Applicant Name - Applicant name on the certificate must be your managed domain. For example, if your domain is named "contoso100.com", the subject name of the certificate must be "contoso100.com". Set the DNS name (alternate subject name) to a wildcard name for your managed domain.
Key Usage - The certificate must be configured for the following uses - Digital Signatures and Key Encryption.
Certificate Purpose - The certificate must be valid for SSL server authentication.

with an example of how to create it.

$ lifetime = get-date
New-SelfSignedCertificate -subject contoso100.com `
-NotAfter $ lifetime.AddDays (365) -KeyUsage DigitalSignature, KeyEncipherment `
-Type SSLServerAuthentication -DnsName * .contoso100.com, contoso100.com

The printer is HP PageWide Pro 477dw MFP, I could not find any real instructions for this printer and the certificates / LDAP. The settings for the printer certificate are:

The file format must be PEM / Base64 encoded (.pem, .cer, .der).

complication: The printer requires an RFC 5280-compliant certificate. I can create an RFC 5280 compliant certificate, but if I do it with the extensions needed by ADDS LDAP, the printer does not check it as RFC 5280 compliant. If I create a certificate without extensions, the printer can properly validate the certificate, but ADDS does not validate it.

Where do I go from here?

Yours sincerely

modding – Need information on several file extensions used by Krome

everything. I was trying to work on a modification for Star Wars: The Force Unleashed, but of course I have to figure out where all the files are and how to get them. So I have some questions about the file structure of this particular game.

  1. Does anyone know a method for opening .pkg files in Star Wars: TFU ISO? I tried several BMS scripts for QuickBMS, none of which worked.

  2. Does anyone know what a .bpk file is or how to open it?

  3. Does anyone know where the compiled code that makes up the game is? This is mainly what I want to change.

I've tried to examine the file hierarchy, file structures, and file types Krome uses in his games, but for the most part, it seems like a mystery. Any help is greatly appreciated!

Field Theory – Definition of the exponent in grief extensions

I searched for Kummer extensions in the context of polynomials $ x ^ n-a $ to the $ a in F ^ * $I followed Lang's algebra and Cohn's Basic Algebra. In both texts I have seen one:

A group $ G $ should be an exponent $ m $ if (1) $ x ^ m = 1 $ for all $ x in G $; (2) There is an ordering element $ m $ in the $ G $,

A Galois extension $ E $ from $ k $ should be an exponent $ m $ if his (Galois) group has an exponent divide $ m $,

Q. So if $ E $ is a Galois extension of the exponent $ m $, then it's Galois extension of the exponent $ 2m $. $ 3m $, and so on …

I did not understand why the exponent of a Galois extension is not defined as a unique integer, namely the exponent of the Galois group.

(What I thought at the time is that there may have been situations in some specific issues where it is known that the Galois extension has an exponent $ m $but it can be an open problem to determine the smallest such integer. But I do not know any reason for that.)

SPFx Extensions Work in the Mobile SharePoint App?

Platform: Mobile SharePoint app

This question may sound silly, but definitely needs to be answered. I've created multiple SPFx Web Parts and added them to pages. These work fine when I try to display them in the SharePoint mobile app (Android). However, SPFx extensions do not exhibit the same behavior.

Solution background:
For security reasons, I'm trying to hide the command bar for the modern list. This works fine in the browser, but the SharePoint app still shows options for list items such as delete, add, and so on.

My observations:
I think the SPFx extension does not work because the same elements do not exist on both surfaces.

The command bar in the mobile app may be different so it does not work

Question:
My observations are correct or not?
Is there any way we can make it work for SPFx extensions in a mobile app?

PHP – Yii2 mcq extensions?

I am looking for yii2 mcq extensions for one of my projects. Give me some goodies
What I am looking for is as follows

-Something with the timing in it.
-Can create a certificate after taking the mcq.

I found something like this, but I could not find any relevant documentation to support it. I can do that right away.
