One of the users unable to login into bitbucket Data center?

[Venkat Jira Admin]

Hello,

We are currently using Bitbucket Data Center and have successfully integrated it with Active Directory (AD). While all users can access Bitbucket with their credentials, one user is encountering an issue. Despite entering the correct username and password, they are receiving an "invalid username or password" error. The AD team has confirmed that there are no issues with the user's AD account. Additionally, the necessary permissions have been granted to the user in Bitbucket. Could you kindly advise on how to resolve this issue?

Thank you in advance for your assistance.

Hi @Venkat Jira Admin 

If the user exists in Bitbucket and enters the correct password while logging in, we should examine the logs to identify the potential cause of the problem. You can activate the debug logs via the GUI and use a curl command to enable two additional debug loggers. After reproducing the issue, review the logs for the specific error.
I am providing the steps to enable and disable the necessary debug logs, but please note that such cases might require further investigation depending on the error. Therefore, I recommend raising a support case to review the issue.

Procedure to Enable/Disable Debug logs:

1. From the UI go to Gear Icon > Support > Logging and Profiling and check Enable debug logging, Profiling and click the Save button.
2. Enable the debug log for the crowd by the below command

   curl -u <adminuser> -v -X PUT -d "" -H "Content-Type: application/json" <Bitbucket_BASE_url>/rest/api/latest/logs/logger/com.atlassian.crowd/debug 
   
   curl -X PUT -u <ADMIN_USERNAME> <Bitbucket_BASE_url>/rest/api/latest/logs/logger/com.atlassian.plugins.authentication/debug
   

3. Try to reproduce the issue.
4. Disable debug logs from the GUI. Go to Gear Icon > Support > Logging and Profiling uncheck Enable debug logging, Profiling, and click the Save button.
5. Disable the debug log for the crowd by the below command

   curl -u <adminuser> -v -X PUT -d "" -H "Content-Type: application/json" <bitbucket_url>/rest/api/latest/logs/logger/com.atlassian.crowd/info
   
   curl -X PUT -u <ADMIN_USERNAME> <Bitbucket_BASE_url>/rest/api/latest/logs/logger/com.atlassian.plugins.authentication/info
   

6. Verify the logs to see the error.
