When I change AD password using ldap I can login using both old and new passwords for few minutes.
Can I disallow logins with old password or is there any way I can reduce validity of changed password to few seconds instead of minutes.

We are resetting the password of Active directory service account used in server for
Identity in Application Pool
Certificate Access Permission
Folder share access permissions
Windows Scheduler job permission
HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > EventLog (Permissions)
Should we modify the all the places after password reset?
No need to reset password for application pool.You can directly entered into application pool but for accessing the sites presents in application pool using identity.You will need new password that you have reset(Indirectly we can say for application pool it auto update the password there is no need of separately change password of application pool).
Windows Domain accounts are used as identities to run IIS App Pools.
Whenever the password of a domain account is changed in the domain
controller, the new password has to be updated individually in all
associated App Pools for web applications to run without any
hindrance. With each domain account running numerous App Pools,
changing all the passwords manally becomes tedious.
Same for Certificate Access Permission, Folder share access permissions, HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > EventLog (Permissions) we don't require change passoword.
It is different for Windows Scheduler job permission we need to change password because in backend Window Scheduler Job is working with old password but all the schedule job will be failed.You need to update the password manually here.

We have a C# web app for new customer intake, at the end of which the user enters a password value we apply to their new Active Directory user object when we invoke the userPrincipal .NET method to create their user object. Our code also creates an account in our Azure AD tenant, with the correct values (ImmutableID) set for Azure AD Connect to import and join both accounts on its next pass (30 minutes AADC cycle wait time not acceptable for our requirements). We sync our password hashes from on-premise AD to Azure AD, and we have password complexity enabled in AD, and we enabled and added our own vocabulary to the Banned Words (substrings) facility in Azure AD. We are considering installing the MS "Password Protection" service on our DC's that will also apply Azure Banned Words checking when passwords are updated on-premise.
To keep this question short, we really would like to pre-validate the user entered passwords against all the password policies, including the banned words list (assume we install that service on all our on-prem DCs), but we can't find a method or service in .NET that will pre-validate that a proposed password passes all the active password policies. Our users tend to use Azure Self Service Password Reset, on-premise password changes later on are rare. But in the C# programming, it appears you have to actually request an Add of a new AD username to get .NET to evaluate the password value and signal status back, from the userPrincipal method in .NET
Anyone got any tricky ideas how to get a password pre-validated against AD password policies without the context of adding an actual new user, but assuming that the sAMAccountName that will be submitted does NOT yet exist in Active Directory? We thought about creating a temporary AD user with hash or base64 of a GUID for a unique temporary usernames, get any password evaluation feedback back from .NET, then delete the temporary user object, but that's a lot of overhead just to check a password, would trigger replications and generate beaucoup EventViewer and AD-AuditPlus log events, much junk network traffic. Thank you.
We are currently testing the feature EnforceCloudPasswordPolicyForPasswordSyncedUsers (https://learn.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-password-hash-synchronization#public-preview-of-the-enforcecloudpasswordpolicyforpasswordsyncedusers-feature) which makes it possible for a tenant to comply to the Azure AD password expiration policy when a user password has expired.
By default, If the customer uses Password Hash Synchronization (PHS), the value DisablePasswordExpiration is set for every user. Which means that If a password is expired on-premise, the user is still able to make use of any Azure AD integrated services. Since we want them to comply the password expiration policy set in AD/AAD, we want this feature configured.
I have this feature working in a LAB environment with a demo M365 tenant.
Situation LAB: 1 AAD Connect Server - 1 M365 tenant - PHS enabled - Specific OU synced - ForcePasswordChangeOnLogOn feature enabled
When I create a new user with the feature enabled, it sets the value to DisablePasswordExpiration, when I initiate a password change on-premise it changes the value from DisablePasswordExpiration to None as expected.
Now the challenge, in the dev environment of the customer.
Situation: 1 AAD Connect Server - 1 M365 tenant - PHS enabled - Specific OU synced - ForcePasswordChangeOnLogOn feature enabled
When I create a new user, it does not have any value set. It should have the DisablePasswordExpiration set, but it doesn't. When I initiate a sync between on-prem and AAD, the value doesn't appear.
When I change the password on-prem for an existing user WITH the value DisablePasswordExpiration value set, it changes the value to "None". So in the above scenario for the feature does not work for newly created users, but does works for existing users.
The feature EnforceCloudPasswordPolicyForPasswordSyncedUsers is enabled in both cases.
When using MS SQL Server, I keep trying to create more logins for the server with their own passwords however as soon as the login has been created, I go back to look at the login settings and see that the password has been reset to some mysterious 15 character password.
As you can imagine, this basically makes the login unusable. I've seen other cases similar to this specifically for the "sa" login however nothing on the creation of custom logins.
I've tried unchecking the "User must change password at next login", "Enforce password expiration", and "Enforce password policy" checkboxes but this has no effect. The one thing that does work is using no password at all, but obviously this is a huge security risk.
MS SQL Server never store your password for security reason. MS SQL Server store only the HASH of your password.
Therefore settings form can't shown the password. Instead it shows
some mysterious 15 character.
I have a requirement to set Password History limit in WSO2 - IS, i.e if my current password is "password1", and if am trying to changing the password with "password1" again, it should not accept.
If I set my password history limit as "3", then the new password should be different from last 3 password for that particular account.
We are using SQL Server as the user store for WSO2.
Also some previous answers for similar question suggests that I need to implement a custom password policy and add it to wso2. Is that true for version WSO2 IS 4.6.0 ?
Also will this policy apply to both "Forgot your password" and "change password" apis of the wso2 sdk? Or only to change password api?
Yes. You are correct. This is not supported by WSO2 Identity Server by default.(Even with latest 5.0.0 version). You need to write a custom password policy implementation by your own to do this. Also, you may need to develop some custom SQL tables to store older password. SQL user store of Identity Server only stores the current password.
