TAC Configuration - Unable to connect to Nexus Artifact repository due to unknown password

We do not know what the current password is for Nexus. How do we change the password ?

Solution:

If you do not know or have forgotten the current password for Nexus, the following steps can be undertaken to reset the password:

1. Stop the "TIBCO Jaspersoft Nexus local server 6.4.1" service

2. Back up a copy and then open the file: 

     C:Jaspersoft6.4.1jacArtifact-Repository-Nexus-V2.14.3-02sonatype-worknexusconfsecurity.xml[/code]

3. Search for 'admin' as the user id and enter 'f865b53623b121fd34ee5426c792e5c33af8c227' for the password. This will give the 'admin' user a password of 'admin123'.  Ensure the status is 'active'.

       <user>
         <id>admin</id>
         <firstName>Administrator</firstName>
         <lastName>User</lastName>
         <password>f865b53623b121fd34ee5426c792e5c33af8c227</password>
         <status>active</status>
         <email>admin@company.com</email>
       </user>

   Note: this follows the steps as per the article in the 'Related Articles" section. 

4. Start the "TIBCO Jaspersoft Nexus local server 6.4.1" service

5. In order to change the password to a different password, open a browser and log in using the nexus url: eg. http://localhost:9081/nexus with the modified password                   'admin123'

   Note: The default port is 8081 but this configuration uses port 9081 instead

6. After logging in, click on the user 'admin' at the top right of the screen and click on 'profile'. You can then click on 'Change Password' to change the password of your               choice. 

   The 'Change Password' button will commit the changes immediately to the security.xml. A restart of the Nexus service is not required. 

7. Revisit the Artifact Repository in the TAC Configuration page and enter in the new password. After clicking on Refresh, the checks will now be successful showing all           green ticks.
