I have 2 clustered filers. One filer shares several vols via
nfs. The security on these vols is set to unix. Some of
them require access from windows in which case a cifs share has been
created and ldap is used to map windows accounts to unix uids/gids.
On the other filer, all vols are ntfs, there's no nfs (cifs only), and ldap is configured and enabled.
We experienced an outage on all cifs connections on both filers when
the one ldap server we were using went down. "net view" (from a
windows client) would hang and explorer couldn't find the network path.
I would expect the mapping to fail and windows users to be mapped to
the default pcuser on the unix vols accessed via cifs. I would
also expect the cifs only filer to have no issues continuing to serve
cifs. Is my expectation off? I can resolve the issue by
adding additional ldap hosts but I want to uncover why cifs only
connections are dependent on ldap when my ad domain controllers are
online.
Thanks, jd
