How do i reset the forgotten password of glassfish server 4

Question

Recently, i change the password for admin, and unfortunately i don't remember the password of my glassfish server 4. How, can i reset the password.

I've followed the instruction provided in the following link "https://superuser.com/questions/7654/how-to-reset-delete-my-glassfish-password", but it didn't help me.

i went to this path "../glassfish4/glassfish/domains/MyDomain/config/" and change the "admin-keyfile" file, but still it didn't help me.

Solution

Finally, after few hours of posting the question, i found a solution. On my glassfish installed directory, this in my case /glassfish4/glassfish/domains/mydomain/config. I edit the file named with file name admin-keyfile. i added this line next to the existing line( but i commented the existing line).

admin;{SSHA}WQVj8i9CLECCiv+w6ZxGgMrcfPqHPoXZW+2Jdw==;asadmin

Then i restart the glassfish server.

Since, i m loading the glassfish server in different machine[Not required if running locally], i additionally need to run this command asadmin enable-secure-admin to make secure enable and asadmin change-admin-password. To set new password. Then i restarted the server again.
Finally it worked.

Once the above commands are executed. asadmin change-admin-password will ask for old password after giving in username. Just press enter and giving new password for next question. new login should work..
