Can not change the CLI password of an Administrator Account

Hi, Recently I tried to change the password of my Administrator Account of F5 using CLI.

 

My_ID@(XXXXXXXX)(cfg-sync In Sync)(Active)(/Common)(tmos) modify auth password My_ID

 

changing password for My_ID

 

new password:

 

confirm password:

 

My_ID@(XXXXXXXX)(cfg-sync In Sync)(Active)(/Common)(tmos) save /sys config

 

Saving running configuration...

 

/config/bigip.conf

 

/config/bigip_base.conf

 

/config/bigip_user.conf

 

Even though is was saved successfully, new password doesn't get accepted in next login. Again and again it only accept old password.

 

Could you please help on this.

 

Thanks.
