Has anyone else had the same problem with SYSMAN password resetting?

Question

I am a Oracle Support Administrator and have posted a SR with Metalink and just wanted to ask the community if they have had any of the same problems.
I am remotely accessing a customers Grid Control via VMWare software and over the past couple of weeks I have been trying to access GC with the Sysman user. The password seems to be either resetting itself or there is a bug in the system. I have checked to see if there is a expiration script running or something similar with no result. It is definitely being altered somehow at the Grid Con end of things. I checked to see if it was resetting in the emon.properties file in the oracle home, this was not the case. So am really stuck.
I have to change the password via SQL+ for it to come back online.
Any ideas or suggestions would be grateful .
Thanks all.

9.2 Changing the SYSMAN Password
The SYSMAN account is the default super user account used to set up and administer Enterprise Manager. It is also the database account that owns the objects stored in the Oracle Management Repository. From this account, you can set up additional administrator accounts and set up Enterprise Manager for use in your organization.
The SYSMAN account is created automatically in the Management Repository database during the Enterprise Manager installation. You also provide a password for the SYSMAN account during the installation.
See Also:
Oracle Enterprise Manager Grid Control Installation and Basic Configuration for information about installing Enterprise Manager
If you later need to change the SYSMAN database account password, use the following procedure:
Shut down all the Oracle Management Service instances that are associated with the Management Repository.
See Also:
"Controlling the Oracle Management Service"
Change the password of the SYSMAN database account using the following SQL*Plus commands:
SQL>connect sysman/oldpassword;
SQL>alter user sysman identified by newpassword;
For each Management Service associated with the Management Repository, locate the emoms.properties configuration file.
The emoms.properties file can be found in the following directory of the Oracle Application Server Home where the Oracle Management Service is installed and deployed:
IAS_HOME/sysman/config/
Locate the following entries in the emoms.properties file:
oracle.sysman.eml.mntr.emdRepPwd=ece067ffc15edc4f
oracle.sysman.eml.mntr.emdRepPwdEncrypted=TRUE
Enter your new password in the first entry and enter FALSE in the second entry.
For example:
oracle.sysman.eml.mntr.emdRepPwd=new_password
oracle.sysman.eml.mntr.emdRepPwdEncrypted=FALSE
Save and exit the emoms.properties file and restart each Management Service associated with the Management Repository.
In the Grid Control console, click the Targets tab and then click All Targets on the sub tab.
Select the Management Services and Repository target and click Configure. Enterprise Manager displays the Monitoring Configurations page.
Enter the new password in the Repository password field and click OK.
See Also:
"Specifying New Target Monitoring Credentials"
After the Management Service has started, you can check the contents of the emoms.properties file to be sure the password you entered has been encrypted.
For example, the entries should appear as follows:
oracle.sysman.eml.mntr.emdRepPwd=ece067ffc15edc4f
oracle.sysman.eml.mntr.emdRepPwdEncrypted=TRUE
