Importing a BSD 4.3 password file

Edit online

You can import a BSD 4.3 password file into AIX®.

To import a BSD 4.3 password file, perform the following steps:
  1. Copy the BSD 4.3 password file to the /etc/passwd file and enter: 
    pwdck -y ALL
  2. Update the /etc/security/limits file with a null stanza for any new users.
    The usrck command does this, but using the usrck command can cause problems unless the /etc/group file is imported with the /etc/passwd file. For more information about the usrck command, see usrck.
    Attention: If the /etc/security/limits file is modified, the stack must not exceed 65,536 bytes. If it does, running the usrck command can cause problems. Change the stack size to 65,536 and run usrck command again.
  3. Run the grpck and usrck commands to verify group and user attributes.
