Three bugs blocked sign-in entirely:
- Login.razor is static-SSR but its form model lacked
[SupplyParameterFromForm], so the posted username/password never
bound — SignInAsync saw empty fields and bailed before LDAP was
contacted. Annotate the model; seed it in OnInitialized since
BL0008 forbids an initializer on a [SupplyParameterFromForm]
property.
- appsettings.json ServiceAccountDn used ou=svcaccts, which GLAuth
reads as a (non-existent) group — the service-account bind failed
with "Group not found". Use cn=serviceaccount,dc=lmxopcua,dc=local.
- LdapAuthService resolved the user DN by searching (uid=...), but
GLAuth keys users by cn. Add an LdapOptions.UserNameAttribute knob
(default cn for GLAuth; set sAMAccountName for Active Directory)
and use it for the search filter.
