thank you!
Enabled users to self register + Assign a **new **database for each new user.
Problem I was calling var result = await base.OnPostAsync(); which registers a user in the host. a new tenant with a admin role with the same email address was the duplicate email.
Solution : I override the post async and remove the RegisterLocalUserAsync which solved the duplicate email. I dont want to store this user in the host
Current Problem: Attached the current code. https://drive.google.com/file/d/10yTLcz5QeiZ8Gy7FulbGPP5YzeOC_2UZ/view?usp=sharing Attached the current logs : https://drive.google.com/file/d/1eu1ukcUamo0Lrd-50aNEpkmWE6YdzlxK/view?usp=sharing
this is needed for a TENANT with a new database to be created. ** await _dbSchemaMigrator.MigrateAsync();**
This line is needed for the USERNAME to have the same name entered in the registration OR else the default admin name "admin" is used. ** await _dataSeeder.SeedAsync(new DataSeedContext(tenant.Id) .WithProperty(IdentityDataSeedContributor.AdminEmailPropertyName, Input.EmailAddress) .WithProperty(IdentityDataSeedContributor.AdminPasswordPropertyName, Input.Password) .WithProperty(IdentityDataSeedContributor.AdminUserNamePropertyName, Input.UserName)); **
If I use both, I get a transient failure to ABP permission grants. How do i resolve the issue?
this is happening every time during the initial registration. Lets say, you have USER100, it will say USER100 is duplicate because the migration are running twice.
DUPS EMAIL ISSUE
I am spinning up a new database with a new user. this is the only user in the whole database. then its says duplicate email found.
What code changes do you suggest? we want to make use of all the code in the base class except make sure to have a seperate db for each user.
This is closely related to the https://abp.io/support/questions/8116/Change-default-admin-name-to-the-provided-USER-NAME-when-creating-a-new-tenant
It didnt completely resolve the problem.
Good News Code below
However, 2 problems **
Duplicate Email Issue
However, I see this error in the logs --> https://drive.google.com/file/d/1-fctzIxKqW5zSgSvLGbjCdaWh31mvWAV/view?usp=sharing
Once we resolve #1, how do we assign custom permission to the admin user. This will be customer facing app - so i dont want the admin to meddle with CMS KIT, View Security Logs, Audit Logs etc. I just want him to look at APP pages that i created + Add new users if he wants to. Is that possible. The code below for permission is a simple prototype I was trying - but even that didnt work.
PLEASE Help.

yes that worked like a charm! thanks you.
Its working when you are adding text, however the button is not rendering. do you have any ideas? I have not added any custom code. Just copy paste the same code from the source module. 
Thanks! 
I was able to get the the test page working too. it could be an issue with the script itself I wonder. atleast I can proceed at this point. Thank you for the fast response
Apologies. I read it as Auth Server (for angular only).
I tried adding that to the blazor project (server) but it didnt work.
I dont have "auth server" project now. How i can add it? 
I already have a solution. Can i add a "auth server" project now? or create a new solution and transfer my code?
I see, makes sense. Let me try that and close this issue
