Switching CurrentTenant to user.TenantId in PasswordSignInAsync without refreshing IdentityOptions meant that lockout, password policy and other tenant-scoped options used host values during the base sign-in call. Call IdentityOptions.SetAsync inside the tenant switch so downstream checks use the user's tenant configuration.
- Override IdentityUserManager.FindByIdAsync to fall back to a cross-tenant lookup in shared user sharing strategy so any caller that hits FindByIdAsync from a non-matching tenant context (including base SignInManager internals for TwoFactorSignInAsync and TwoFactorRecoveryCodeSignInAsync) can still resolve a tenant user by id
- Drop the now-redundant AbpSignInManager.GetTwoFactorAuthenticationUserAsync override; the base implementation works automatically through the new FindByIdAsync behavior
- Cover the new FindByIdAsync behavior with unit tests
Guards against regressing the data-access contract behind the 2FA redirect bug: login must find a tenant user by user name from a host context, and the 2FA mid-flow must then resolve the same tenant user by id from the same host context.
Exercises the full cookie round-trip: writes a TwoFactorUserId cookie carrying a tenant user id, then verifies that AbpSignInManager.GetTwoFactorAuthenticationUserAsync returns the tenant user when CurrentTenant is null.
- Add IdentityUserManager.FindSharedUserByIdAsync to resolve a user by id across tenants in shared user sharing strategy
- Override AbpSignInManager.GetTwoFactorAuthenticationUserAsync to use it so the 2FA mid-flow can still find a tenant-scoped user when CurrentTenant is host
- Cover the new method with unit tests
Introduces `IsAvailableAsync()` to `IResourcePermissionManagementProvider` and `IResourcePermissionProviderKeyLookupService`, allowing providers to opt out in certain contexts.
`ResourcePermissionManager` respects this flag in permission checks, writes, and UI lookup service listing.
OpenIddict and IdentityServer client providers override `IsAvailableAsync()` to return `false` when the current context is a tenant (host-only concept).
