Resetting Admin UserName And Password

To know How to Decrypt WebLogic Password ? 

Many times we want to Alter WebLogic Admin Username and passwords on a Routine Basis…

If you want to Reset The WebLogic Username and Password then Please follow the Steps mentioned Below…(EXACTLY):

Step1). open a Command Prompt and then run “setDomainEnv.sh” or “setDomainEnv.cmd”.

Step2). Just for Safety Take a Backup of (C:\bea103\user_projects\domains\7001_Domain\security\*DefaultAuthenticatorInit.ldift*) file …because in the Next Command which we are going to run is going to Create a New File “DefaultAuthenticatorInit.ldift”.

Step3). In the Command Window Move inside your Domain’s Security Directory…And then Run the Following Command:

Example: C:\bea103\user_projects\domains\7001_Domain\security>java weblogic.security.utils.AdminAccount newAdmin newPassword .

Syntax: java weblogic.security.utils.AdminAccount <NewAdminUserName> <NewAdminPassword>

NOTE:- There is a . (DOT) at the end of the Above command which represents the Current Directory. Here you can see that after this command Executes A new “DefaultAuthenticatorInit.ldift” file will be created in the Current Directory.

IMPORTANT STEP   [This Step 3-A) U Need Not to Follow If you Already Forgot your Admin Credentials]

Step3-A).  Login to Admin Console

Security Realms—> myrealm(Your realm Name)—> Migration(Tab)—> Export (Tab)

Here please provide a Directory location for “Export Directory on Server:” TextBox (Example: C:\UserData)

Click on “Save” button…you will find that in the Directory which you have specified you will get :

DefaultAuthenticator.dat

DefaultCredentialMapper.dat

exportIndex.dat

XACMLAuthorizer.dat

XACMLRoleMapper.dat

Step 4). In the Same command prompt Move inside the admin Server folder inside your domain. And then Just remname the “data” folder to something else ….like “data_OLD” this is a way of taking safe backup….

Example: C:\bea103\user_projects\domains\7001_Domain\servers\AdminServer> rename data data_OLD

Step 5). Now Similarly rename the boot.properties as well to an other File….

Example: C:\bea103\user_projects\domains\7001_Domain\servers\AdminServer\security> rename boot.properties boot.properties_OLD

Step 6). Make sure that “boot.properties” file exists….If yes then Now start The Admin Server….

While starting it will ask for the UserName and Password to be entered as ..we havenot created any “boot.properties” file at present. But it is always recommended that u create the “boot.properties” file on your own …to prevent WebLogic Prompting you for Admin Username & Passwords while starting the Server.

————> At the End Login to Admin Console with the New Useraname and Password—–> Check the Users in Security realms …you will not find any user with name “weblogic” There….

This is most important Step:  Because Sometimes we face this kind of issue if you have provided a Wrong format in your “boot.properties” file there should be NO Special Charachers (UTF or Invisible sharacters) Or NO Space in your “boot.properties” file …except below two Lines:

    username=MyAdminUserName

    password=MyAdminPassword

Please edit this File very carefully….better use Noteopad kind of Simple Editors.

Use “ls” (Unix command) or “dir” Windows Command to Make Sure that the File Extension is “boot.properties” only…and not “boot.properties.txt” or something else.

Note: There should be No Heading Or Trailing SPACE character in these two Lines.

Step 7).  To import other User Data back Please do the following:

Login to Admin Console

Security Realms—> myrealm(Your realm Name)—> Migration(Tab)—> Import (Tab)

Now provide the folder Name where u have all the above files:

DefaultAuthenticator.dat

DefaultCredentialMapper.dat

exportIndex.dat

XACMLAuthorizer.dat

XACMLRoleMapper.dat
