So far I have always been able to log in successfully via sso.
cf login -a url --sso
I need another way to log in for my pipeline script and tried the following command.
cf login [-a API_URL] [-u USERNAME] [-p PASSWORD] [-o ORG] [-s SPACE]
This command does not work with my user, nor with a technical user to whom all necessary roles have been assigned (M D A). I get the following message.
API endpoint: url
Password>
Authenticating...
Credentials were rejected, please try again.
Does anyone know how to solve this problem?
Or maybe an alternative to create a gradle task, for example, that can be executed in a jenkins pipeline.
At the end, I want to automate a deploy (to cloud) of an artifact with my Jenkins pipeline.
You provided —sso flag, so you shouldn’t see a password prompt. Instead you should be given the url to get a token.
Maybe your CF has been misconfigured and does not support SSO yet. I tried to fix the CF CLI to avoid this but it was oddly rejected https://github.com/cloudfoundry/cli/pull/1624
Try fixing your CF installation (it needs to provide some prompts), or skip the —sso flag usage.
Using --sso and -u/-p are not doing the same thing on the backend, and there's no guarantee that a user which can login through SSO is also set up to login as a user stored directly in UAA. UAA has multiple origin's from which users can be loaded, like SAML, LDAP and internal to UAA. When you use the --sso flag, you are typically logging in via a user from your company's SAML provider. When you use the -u/-p flags, it's typically LDAP or UAA, something UAA validates directly.
In order for what you are trying to do to work, you would need to have a user available with an origin in SAML (for --sso) and a user in origin LDAP or UAA (internal), and technically those would be two separate users (despite the fact that they may have the same credentials).
At any rate, if you normally login with the --sso flag and you want to automate work, what you really want is to get a UAA client that is set with the grant type of client credentials. You can then use cf auth CLIENT_ID CLIENT_SECRET --client-credentials to automate logging in.
Typically you don't want your user account to be tied to pipelines and automated scripts anyway. If you leave the company and your user get deactivated then everything breaks :) You want a service account, and that is basically a client enabled with the client credentials grant type in UAA.

I am using keycloak operator to install keycloak and i have configured keycloak to use external database (RDS instance). ==> (externalDatabase: true)
The keycloak instances are up and running without any issues.
When i tried to login to the keycloak UI with master realm credentials it is telling that the credentials are invalid, though the credentials are correct.
I am getting the credentials using the following command.
kubectl get secret credential-test -o go-template='{{range $k,$v := .data}}{{printf "%s: " $k}}{{if not $v}}{{$v}}{{else}}{{$v | base64decode}}{{end}}{{"\n"}}{{end}}'
The following is the log from the instance.
07:40:48,172 WARN [org.keycloak.events] (default task-1) type=LOGIN_ERROR, realmId=master, clientId=security-admin-console, userId=566f4e3e-c0f1-4304-bca2-686321d88b87, ipAddress=10.242.3.61, error=invalid_user_credentials, auth_method=openid-connect, auth_type=code, redirect_uri=https://test123.net/auth/admin/master/console/, code_id=5561bc9e-e2b9-41e3-836d-37add6e74c1c, username=admin, authSessionParentId=5561bc9e-e2b9-41e3-836d-37add6e74c1c, authSessionTabId=Oq-orhggRE4
Any advice or suggestion is highly appreciated.
I had this, or a similar issue as well when setting up the operator.
It appears that the external database that supposedly stores the admin username and password isn't updated when a new secret is generated if, say, the CRD for the Keycloak instance is deleted along with the secret. The steps I went through to fix it was to:
Delete the CRD.
Delete the database.
Recreate the database.
Recreate the CRD.
That way, the database should have no reason to accept the new credentials.
There is probably a better solution. But I could not find it in the docs so far.

How to configure Jenkins credentials with Github Personal Access Token
How to clone Github repo in Jenkins using Github Personal Access Token
So this is the problem
The alternate solution that I am aware of
SSH connection
username password configuration in Jenkins. However,
use of a password with the GitHub API is now deprecated.
But My question is how to setup Github connection with Jenkins using Personal Access Token
[UPDATE]
The new solution proposed by git is
https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/
Which says:
Beginning August 13, 2021, we will no longer accept account passwords
when authenticating Git operations and will require the use of
token-based authentication, such as a personal access token (for
developers) or an OAuth or GitHub App installation token (for
integrators) for all authenticated Git operations on GitHub.com. You
may also continue using SSH keys where you prefer.
What you need to do:
https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/#what-you-need-to-do-today
Basically, change the add URL as
https://<access token>#github.com/<userName>/<repository>.git
Something like this
https://<access token>#github.com/dupinder/NgnixDockerizedDevEnv.git
and set the credentials to none.

[OLD Technique]
After many discussion on multiple threads from Stackoverflow
I found one thread that is useful.
Refer to this answer:
https://stackoverflow.com/a/61104603/5108695
Basically
Personal access token can be used as a password, as far as Jenkins is concerned at least. I added new credentials to the credential manager.
Go to Jenkins
Go to credentials > System > Global credentials > Add credentials a page will open.
In Kind drop-down select Username and password.
In User put a non-existing username like jenkins-user or user.
Add Personal Access Token in the password field
Now start configuring your project.
source code management tab, select new configured credentials from Drop-down near credential Under Repository URL
So this is how we can configure or setup Authentication between Jenkins and Github using Personal Access Token
References:

Change jenkins pipeline to use github instead of gitlab
The accepted answer wont work anymore because of this: https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations.
You will need to:
Change the URL of the repo to: https://<access token>#github.com/<user-name>/<repo-name>.git (Replace every <...> with the real parameters)
Set the credentials to none.
As of August 2021 the answer posted by Dupinder Singh is accurate. The only thing I would add is that if you are part of a team, the url format appears to be a bit different. This is what worked for me:
https://<access token>#github.com/<team>/<repo>.git
for example
https://ghp_6dh3jdk394jsmbh299jjdg20fh87hd83ksk39#github.com/MyKuleTeam/KuleGuyCode.git
Note that if you use a personal access token you don't need to have any github credentials stored in jenkins.
As for credentials for Jenkins Github Plugin, please be aware only Personal access tokens are now accepted by this plugin.
To generate such a token, follow the Github docs (e.g. here). Don't save it, it can be regenerated in Github and updated in Jenkins if lost or when migrating to a different server.
To add the token do Jenkins credentials store, go to <JENKINS_URL:PORT>/credentials/store/system/domain/_/newCredentials and select Kind "Secret text" (not the default "Username and password"), then paste the token as Secret and choose some ID.
Testing: the credential should appear on the list of Credentials at <JENKINS_URL:PORT>/credentials/ and be selectable from the drop-down list at <JENKINS_URL:PORT>/configure/, where pressing the "Test connection" button should display "Credentials verified for user <GITHUB_USER>".
More info: see the Github plugin docs.
Caveats: Git Plugin has its long-standing issues, so if the newly created "Secret text" does not appear in your pipelines, try if this solution helps (with "the user who triggered the build" considered safer than "SYSTEM"):
client-and-managed-masters/why-credentials-are-not-listed-in-the-git-scm-section
There is (yet another) way to do this as of 2020/04 which is supposed to be superior to personal access tokens. The best part is that you can continue using a username/password-style credential, and the plugin will handle authenticating with GitHub in the background.
Benefits include:
Larger rate limits - The rate limit for a GitHub app scales with your organization size, whereas a user based token has a limit of 5000 regardless of how many repositories you have.
User-independent authentication - Each GitHub app has its own user-independent authentication. No more need for 'bot' users or figuring out who should be the owner of 2FA or OAuth tokens.
Improved security and tighter permissions - GitHub Apps offer much finer-grained permissions compared to a service user and its personal access tokens. This lets the Jenkins GitHub app require a much smaller set of privileges to run properly.
Access to GitHub Checks API - GitHub Apps can access the the GitHub Checks API to create check runs and check suites from Jenkins jobs and provide detailed feedback on commits as well as code annotation

I'm creating a Express.js REST server that can invoke and query chaincodes (similar to the JavaScript fabcar example). I'm wondering how would I register, enroll, and use a network user that is based on a username and password, so that I could allow the user to login using their username and password and can invoke chaincodes with their network user.
Please tell me if I'm going about this the wrong way, or if there are configs to achieve this.
I created a repository on hub.docker.com and now want to push my image to the Dockerhub using my credentials. I am wondering whether I have to use my username and password or whether I can create some kind of access token to push the docker image.
What I want to do is using the docker-image resource from Concourse to push an image to Dockerhub. Therefore I have to configure credentials like:
type: docker-image
source:
email: {{docker-hub-email}}
username: {{docker-hub-username}}
password: {{docker-hub-password}}
repository: {{docker-hub-image-dummy-resource}}
and I don't want to use my Dockerhub password for that.
In short, you can't. There are some solutions that may appeal to you, but it may ease your mind first to know there's a structural reason for this:
Resources are configured via their source and params, which are defined at the pipeline level (in your yml file). Any authentication information has to be defined there, because there's no way to get information from an earlier step in your build into the get step (it has no inputs).
Since bearer tokens usually time out after "not that long" (i.e. hours or days) which is also true of DockerHub tokens, the concourse instance needs to be able to fetch a new token from the authentication service every time the build runs if necessary. This requires some form of persistent auth to be stored in the concourse server anyway, and currently Dockerhub does not support CI access tokens a la github.
All that is to say, you will need to provide a username and password to Concourse one way or another.
If you're worried about security, there are some steps you can most likely take to reduce risk:
you can use --load-vars-from to protect your credentials from being saved in your pipeline, storing them elsewhere (LastPass, local file, etc).
you might be able to create a user on Dockerhub that only has access to the particular repo(s) you want to push, a "CI bot user" if you will.
Docker Hub supports Access Token
goto Account Settings > Security
its same as Github personal access token (PAT)
You can use this token instead of actual password
I am able to authenticate radius users using radius server+pam+ssh with creating local user with blank password in linux.
Is it possible to authenticate radius users without creating users in local machine with blank password?
/etc/pam.d/ssh file as below
#%PAM-1.0
auth sufficient pam_radius_auth.so debug
auth sufficient pam_unix.so use_first_pass
auth required pam_auth_status.so
account sufficient pam_unix.so
account required pam_auth_status.so
session required pam_unix.so
You can authenticate the user without creating an entry for him in /etc/passwd and /etc/shadow files. But now , the user is not associated with any shell in '/etc/passwd' , so it can be of no use.
Do you want to launch a shell after authentication or you want the user just to be authenticated?
I found two nss libraries that could help in this case:
libnss-mapuser from Cumulus Linux.
libnss-ato
The general process is that these will map unknown (but authenticated) user to a single user template. Each user will get his/her own /home folder though but both libs have in common that the user id will be the same.
These packages are mainly targeted at network devices where there is no ldap setup done. Cumulus describes the setup nicely.
I recommend reading https://serverfault.com/questions/538383/understand-pam-and-nss to understand what is happening there.
