Which parameter in the smb.conf defines how long the winbind daemon will cache user and group information?

The `winbind cache time` parameter in the `smb.conf` file directly specifies in seconds how long Winbind will cache user and group information obtained from a directory service, such as Active Directory or LDAP. This setting improves performance by reducing the frequency of external lookups, balancing efficiency with the need for up-to-date identity data.

`idmap cache time` is not a standard `smb.conf` parameter for Winbind's general user/group cache; it's related to ID mapping caching, not the daemon's lookup cache.

`cache time` is too generic and not the specific parameter used by Winbind for its user and group information cache.

`nscd cache time` refers to the `nscd` (Name Service Cache Daemon) configuration, which is a separate system caching mechanism from Winbind's internal caching.
