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

The `winbind cache time` parameter in `smb.conf` controls the duration, in seconds, for which Winbind stores retrieved user and group information in its cache. This caching mechanism significantly reduces network traffic to domain controllers and improves the performance of user and group lookups on the Samba server.

`idmap cache time` is not a standard `smb.conf` parameter for Winbind's general user and group information cache; it relates to ID mapping specific cache settings.

`cache time` is a generic term and not a valid `smb.conf` parameter for Winbind's caching duration.

`nscd cache time` refers to the caching duration for the Name Service Caching Daemon (`nscd`), which is a system-wide service, not a specific Samba or Winbind parameter in `smb.conf`.
