This request is Add a custom field option for Subject Name format for "Build from this Active Directory information" on a user certificate template.

Build from this Active Directory information is an important feature for many companies using Active Directory Certificate services as it ensures the user account can't create their own values on a certificate , which could mis-represent the identity and create security concerns. This is also an important option used for auto enrollment of user certificates.

Currently the only options for this section are Common Name or Fully Distinguished name or None.

This Feature request is to add a custom field option to "Build from this Active Directory information" for a user certificate template so that an admin can add other AD attribute values for Subject Name.

The AD attribute value would use a <> delimiter, like this
<AD Attribute>

to notate the AD attribute and also to allow combining values or other text parameters.
This is similar to other ADCS settings that can create CRL publishing values for example. If the AD Attribute is empty the certificate could be expected to fail as other values that may be missing on a user certificate template.

For example, if we want just the DisplayName to be added to subject name, the admin only would enter in <DisplayName> in the custom field.
If the admin wanted to just add in SamAccountname, the admin would put in that value <Samaccountname> into the custom field.

If the admin wants to combine values with other text , they could enter it in using the delimited AD attribute values with whatever other custom text they would want to add.

Example 1
If the admin wants to have a user's givenName and surname attributes with a space between each value as the certificate subject, they would enter it into the custom field like so:
<givenName> <sn>

So if user's givenName value was Joseph and sn was smith, the above cert would show a subject of:
Joseph Smith

Example 2
If the admin wanted a - in between Displayname and samaccountname, they could do this

<DisplayName>-<Samaccountname>
If the user's Display name is Joseph Smith and their samaccountname is abc123 the cert subject name would be

Joseph Smith-abc123

Feature Request Background

The reasons for this request is that AD Common name or DN's may not be in a format that makes it easy to read the certificate names for a person. A company may have very unique values for CN that may not look human friendly.

For example, take the example of a very large company. There may be 1000 John Smith's or many name change operations to perform. To create uniqueness the AD common name may have more random values, for example JS123456 versus Joseph Smith. The effect of this is particularly impactful for document signing that displays the certificate subject name which may look random to a user. Someone reading the signed data may see the Subject name and think that it is not Joseph Smith, as users may not inspect on other attributes in the certificate (for example, email,etc).

I have a team of engineers working towards PowerShell Modules that we need to upload to PowerShell. We have a work group email address for our team. We would like to use this group email address to upload our modules. I spent quite some time on Azure Active Directory but it only allows me to login using my work email address. I do not see any option to create an account with group email address or add it anywhere. We have done the same using "Manage Organization" feature in nuget.org for our nuget packages. Please help since we do not want to use our individual work email addresses while uploading packages and making future releases.

Their exists a scenario with ADFS and SSO based apps (to include 365) where there is a common user logged into their PC but need to access their webmail. However it detect the user logged and and wants to leverage WIA. Current work around is to do a REGEX and push user agent string to those impacted PCs to not perform WIA and results in Forms Auth. However with Microsoft pushing Edge and Chromium going towards client hints, this bandaid is slowly loosing its adhesive.

Ideally it would be nice to specify a group and force them to forms based auth in lieu of WIA. That plus a link to include private mode and then users could log in and check mail, etc while staying logged into the endpoint via the common kiosk account

When I try to use Get-Help with any of the aboutActiveDirectory* topics, it just gives me a list of cmdlets. Other topics, like aboutFor or about_Break work as expected. I had originally thought it was perhaps an interop issue with PowerShell 7 being installed as well, but it happens when I try it on my Domain Controller that has only the PS built in to the server. An example is below:

PS C:\Windows\system32> Get-Help -Name about_ActiveDirectory

One change to security for incorrect password entry that would make it friendlier for the users and more secure against brute force password attacks would be to use a geometrically increasing delay when a specific number of wrong passwords are entered. The first delay could be one minute, the second 5 minutes, the third 25 minutes, the fourth 125 minutes, etc. Of course this would also involve a time setting for resetting the wrong passwords progression after a previous delay. This would make the initial delay for wrong passwords very short for the user, but would increase the time for a brute force attack to guess the possible passwords from months to years.
