Cannot create new connection or login to added user? - oracle11g

I am using Oracle SQL Developer to connect to Oracle Express 11g and create a new user. I keep on getting the same error when I try to create a new connection (and test it) or when I try to login with a newly created username and password (mad by right-clicking "other users" table in default connection "xe")
The error-
Failure - Test Failed: ORA-01017: invalid username/password; logon denied
How can I fix this issue ?

Seems you're using an user with not enough privilegies, try with "system" user.
That should solve your problem.
Verify the priviligies of the user you created.

(UPDATED) Published blazor wasm app fails to connect to Postgresql

Update 2: this solved the issue for me: https://dba.stackexchange.com/questions/83984/connect-to-postgresql-server-fatal-no-pg-hba-conf-entry-for-host
Also had to make sure I added an https address in the Urls entry in appsettings.json
Update: if checked Postgres logs and found this:
2022-05-09 21:57:59.816 PKT [11284] FATAL: password authentication failed for user "safzal"
2022-05-09 21:57:59.816 PKT [11284] DETAIL: Role "safzal" does not exist.
Connection matched pg_hba.conf line 89: "host all all ::1/128 scram-sha-256"
"safzal" is my PC username but not the username I configured in connection string. Why isn't dotnet using my connection string?
I am making a Blazor wasm (hosted) app with Postgres db. During development, I put connection string without mentioning userid or password in appSettings.json. I used user secrets to store userid and password and linked them in Program.cs. This approach worked fine, I was able to use dotnet ef migrations add myMigration and dotnet ef database update. I was able to use the app normally during development.
However, when I publish, I cannot get the db connection to work. The app loads fine but as soon as I attempt data access it shows "An unhandled error has occured." with option to Reload.
I get the following http 500 internal server error error in browser console:
I was initially using IIS to attempt to run the app. When I tried to run it via Kestrel it shows this error:
fail: Microsoft.EntityFrameworkCore.Database.Connection[20004]
An error occurred using the connection to database 'fistepsdb' on server ''.
fail: Microsoft.EntityFrameworkCore.Query[10100]
An exception occurred while iterating over the results of a query for context type 'fisteps.Server.Data.AppDbContext'.
Npgsql.NpgsqlException (0x80004005): No password has been provided but the backend requires one (in SASL/SCRAM-SHA-256)
I have already tried:
Putting userId and password directly in connection string
Putting connection string in VS2022 Publish dialog > Show all settings > Settings > Databases > [Password, PostgreSqlConnection, UserId]
Putting connection string in IIS > Sites > Default Web Site > Management > Configuration Editor > Section: connectionStrings (though I am unsure about providerName here).
Any help would be most appreciated.

Wso2 admin/admin failing after changing to mysql datasource

I was facing issue while login to Carbon Management Console
Version; WSO2 IS 5.10. 0 as Key Manager
Changes:
I have made Mysql database changes for WSO2AM_DB, WSO2Shared_DB,WSO2User_db in deployment.toml file.
When i tried login Management Console with default admin/admin credentials, I am getting error in UI:
Login failed! Please recheck the username and password and try again.
ERROR {org.wso2.carbon.core.services.authentication.AuthenticationAdmin} - System error while Authenticating/Authorizing User : com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
Also user store changes in deployment.toml cause error
Changes:
[user_store]
type = "database"
[user_store.properties]
TenantManager="org.wso2.carbon.user.core.tenant.JDBCTenantManager"
ReadOnly=false
ReadGroups=true
WriteGroups=true
scim_enabled = true
[realm_manager]
data_source = "WSO2USER_DB"
com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure normally means the configured database is not accessible.
Did you define the database.user configuration in the deployment.toml according to WSO2 jdbc user configuration guidelines? If this is already configured, check the configured connection url and network connectivity from WSO2-IS to userstore database.

How to access SQL Server database from iccube builder

I am trying to connect to SQL server from iccube Web UI, but when I set up the Data Source connection like this
Name: TestDataBase
DriverType: SQL Server
ServerName: localhost
DB Name: TestDataBase
User: MyWindowsUserName
Password: **********
(my windows username and password).
, I got the following error:
JDBC connection for url 'jdbc:sqlserver://localhost:1433;databaseName=TestDataBase;' and user 'MyWindowsUsername' cannot be created due to error 'Login failed for user 'MyWindowsUsername'.
What am I missing, and can I somehow use integratedSecurity so I can login with my windows credentials as I do from SQL Server Management studio.
You can try to setup the connection string as mentionned by Hermes (or here) using the "Server Name" and "DB Name" to define the actual JDBC class name and connection string (check the help icons closed to each fields):
Hope that helps.
Try
jdbc:sqlserver://localhost:1433;databaseName=TestDataBase;integratedSecurity=true;

Not able to get nJupiter.DataAccess.Ldap work with our Internal LDAP (Lotus Domino)

I've tried everything possible, to setup nJupiter.DataAccess.Ldap as the membership provider on our intranet based web application built using asp.net 3.5.
Challenges I am facing:
Not able to authenticate the user using the default login webpart (says Your login attempt was not successful. Please try again)
I tried this code and I receive a COMException : "There is no such object on the server."
var ldapMembershipUser = System.Web.Security.Membership.GetUser("username") as LdapMembershipUser;
if (ldapMembershipUser != null)
{
var givenName = ldapMembershipUser.Attributes["givenName"];
}
I have placed my web.config and the nJupiter.DataAccess.Ldap.config here:
web.config : http://pastebin.com/9XdDnhUH
nJupiter.DataAccess.Ldap.config : http://pastebin.com/WsSEhi98
I have tried all possible permutations and combinations for different values in the XML and i am not able to take it forward. Please guide. I just am not able to connec to the LDAP and authenticate the user or even search for users.
Just looking at your config is unlikely to be enough since I don't know your Domino server's confguration, so my answer isn't an attempt to fix your problem. It's an attempt to teach you how I would approach it if it were my problem. Here's what I do to troubleshoot connections and queries from code to Domino LDAP:
Configure the Domino LDAP server for logging the highest level of debug information with the notes.ini setting LDAPDEBUG=7. See this IBM technote for more info.
Use an LDAP client and figure out how to successfully connect to the Domino LDAP server. I like the free Softerra client for this. Check the logs and save off the info from your successful connection.
Now run your code and compare what you see in the logs against the successful connection.
If the code is making it past authentication but failing on the query, then find the actual query in the log, go back to your LDAP client, figure out what the query should have been, and adjust your code's configuration appropriately.

Unable to use asp.net Web Site Administration Tool SQL connection error

I am working on IIS 7, SQL Express 2008.
I'm trying to use the Web Site Administration Tool to set up some users in a membership db. I have the tables set up but when I click on the security tab in the web app I get an exception "There is a problem with your selected data store..." the error i get is
"The following message may help in diagnosing the problem: Cannot open database "ticketinventory" requested by the login. The login failed. Login failed for user 'sa'"
The connection string I am using is "data source=kyrian-pc\sqlexpress;Initial Catalog=ticketinventory;Persist Security Info=True;User ID=sa;Password=******;"
(I know to not use sa for a connection string, this is just to get it to work initially and I have removed the password with ** )
I can log into sql with the sa username and password and query the membership tables. If I change the querystring to a fake user name I see the error message in the web app reflect that username so I know it is using the right connection string.
As far as I can tell this should be working but I am obviously missing something. Any ideas?
EDIT
It turns out the issue has something to do with my connection string itself. I created a test page with this code
using (System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString))
{
conn.Open();
conn.Close();
}
and this throws a login exception. For whatever reason my other connection string are being stored in the appSettings so there is some difference that I am now trying to work out.
Despite checking it 5 or 6 times I had the db name wrong in the connection string. Problem solved.
