Eclipse Git (Egit) not accepting remote username and password

Question

Why doesn't Egit accept username and password when fetching from remote?

These are the steps I follow:

1. In Git Repositories view I expand Project -> Remotes -> origin
2. Right click on origin -> fetch
3. Login mask appears; I insert User and Password
4. Repeat step 3 other two times
5. An error message appears: https://companyname.visualstudio.com/.../projectname: not authorized

Credentials are correct and I am authorized because I use them daily with any kind of git interface: TortoiseGit, SmartGit, Git Bash, ...

I did research but didn't find this problem. Also similar questions don't address this problem.

---

Update: I used a workaround following this guide. I created an access token from the Visual Studio Team Services account and I'm using that as password.

My git installation is using Git Credential Manager (GitHub page, Microsoft guide to GCM) to store credentials, in fact when I ran for the first time git through the interfaces I mentioned above and tried to connect to the Team Services Git repository the Microsoft Account login window popped up and that was it. Also I can tell it from runnig the command git config --list and getting credential.helper=manager.

Eclipse has the Team Explorer Everywhere plug-in installed, so it should interact with Git Credential Manager and accept the Microsoft Account credentials, but it doesn't. So this is still an open issue.

is your git server setup with your username and password (locally) or what? are you thinking that it will use your AD credentials ? how is the authentication and authorization solution setup ?? – Phaih

do you use the TFS plugin for eclipse? msdn.microsoft.com/en-us/library/hh301122(v=vs.120).aspx – Phaih

Answer 1

I was facing the same issue

From git side settings-->developer settings-->Personal access tokens-->generate new token-->copy that token and use that token as password.

What permissions does Eclipse need for the token? – Tilford

If you are using SSO, you also need to click on the Authorize SSO button after generating the new PAT. – Handbook

Oh, that's exactly what I've needed: Eclipse was saying about password, not token. Now it works. Many thanks to you! – Rossiya

Answer 2

The way to fix this is to go to

Window->Preferences->Team->Git

And then change the HTTP client from Apache HTTP to Java Built-in HTTP

Answer 3

The Git clients you mention uses "native" git, and the credentials are provided transparently during the communication with the server.

Eclipse git client (jgit+egit) is full-java based, and unfortunately you can't use native git in Eclipse.

Either your Git server has user+password locally (not so enterprise-ish!) or you could use Kerberos tickets in Eclipse git; but before you run Eclipse you should do a kinit to create a ticket with your user logon, that is accessible from java process. (Normally the ticket is in your user home directory)

Example using kinit:

I m not so sure about the TFS plugin, but maybe in your case it is worth to install it and see if it helps you instead of the embedded egit, see https://msdn.microsoft.com/en-us/library/hh301122(v=vs.120).aspx

Why can my teammates use Eclipse to connect to remote without running any of these steps? Btw, I'm not the server manager and our operating system is Windows. – Sadesadella

Ok but using above did not help? or you did not try? you can start eclipse in debug mode and see all network exchange (http and https), see what's going wrong etc. Check ssl log, maybe you need to import ca certificates to you cacert. – Phaih

Git clients I mentioned use Git Credential Manager to accept and store Microsoft Account credentials. See update for details. – Sadesadella

@Sadesadella from what I know, there is no official release of jgit that supports the Git credentials manager! It is not (yet) implemented! And definitly not bundled in any eclipse version! (I should know that ;) .. did you try anything from my previous comment? – Phaih

I tried TFS plugin, it installs Team Explorer Everywhere. I don't know how to run Kerberos commands or kinit in Windows. – Sadesadella

See the installation path of your jdk/bin... %java_home%/bin.... where javac is located – Phaih

No, I get the IllegalArgumentException: Can not obtain principal name – Sadesadella

Credentials cache C:\Users\<pcuser>\krb5cc_<pcuser> not found. – Sadesadella

Current ID access: 0: 0x3e710 Tickets memorized in cache: (0) – Sadesadella

Seems so. filler filler – Sadesadella

I m thinking how to get thru this without a lot of conf and settings, could use keytabe, krb5 conf, ini, etc. But it needs that you know what you do, and I "can not" write all steps. ;) ... What does the klist shows for your team mates ? how do you logon to windows? who is administrator? is it enterprise setup? can you install kerberos ui, web.mit.edu/kerberos/dist ? – Phaih

I can't run commands on their pcs... I logon with username (not microsoft, just pc username), I'm administrator, it's not enterprise setup it's a standalone pc. – Sadesadella

does this mean you have a local user/password ? no AD login, you dont logon to a domain during logon on your windows pc? Well, I saw the token solution too, and I think you have to stick to it. As mentioned the jgit has no implementation to the (native) git cred.manager. Check also this url, and see if you find anything that helps #15331666 – Phaih

Answer 4

I had the same issue, not able to update the username in eclipse pop up while pushing to Git. Irrespective of username, I have provided the generated git credentials password and it worked.

Answer 5

Use personal access token for https. Fine graned tokens are preferred.
