Cached uid on autofs filesystems

Question

We have some issues with homedirs on our NFS server (SUN S7110). When we change the owner of a file it seems the old uid is cached. The ls -l still shows the old uid. On other systems which mount the same homedir the has the new uid. Is there a caching mechanism or something like that?

We use opensolaris B134 and autofs to mount the homedirs.

Thanks, Martijn

Yes, attributes such as uid are cached by the NFS client. On Solaris & OpenSolaris the options to control how long they're cached are documented in the mount_nfs(1m) man page - see the option names starting with ac like actimeo and the later man page sections they reference, such as File Attributes and Specifying Values for Attribute Cache Duration Options.
