If you cannot log in to a BMS due to password expiry, contact the operation administrator.

If you can log in to the BMS, perform the following operations to set the password validity period:

1. Log in to the BMS OS and run the following command to query the password validity period:

   vi /etc/login.defs

   The value of parameter PASS_MAX_DAYS indicates the password validity period.

2. Run the following command to change the value of parameter PASS_MAX_DAYS in 1:

   chage -M 99999 user_name

   99999 is the validity period of the password, and user_name is a system user.

   You are advised to set the password validity period as needed and change it on a regular basis.

3. Run vi /etc/login.defs to verify that the configuration has taken effect.
