Operating Systems Solaris Enabling time service in local zones Post 302477011 by ERahman on Friday 3rd of December 2010 04:40:27 AM

It appears that ntp cannot be run from a local zone:

You'll find that ntp in a non-global zone doesn't actually work. This
is because adjtime(2) is restricted to the global zone.

Dear all,

I know from sol10 faq that only global zone can be as ntp server. I already tested that ntp client also work in global zone, but I fail to make ntp client work in local zone. Any idea how to sync time local zone to at least global zone or to free ntp time server

Nawir,
Zones don't each have an independent notion of time-- see the zones FAQ entry entitled "Q: Can some non-global zones have different date and/or time settings (i.e. different clocks)?"
So "zone time" is always exactly the same as "global zone time", so there is no need to run an NTP client in a zone; just run it in your global zone. One less thing to worry about.

Q: Can some non-global zones have different date and/or time settings (i.e. different clocks)?

A: Although different zones can ’be’ in different time zones, each zone gets its date and time clock from the same source. This means that the time zone setting gets applied after the current time data is obtained from the kernel.
If you would like the ability to have different clock sources per zone, please add a call record to RFE 5033497. [August 2010]

NAME

       idmapd - Native Identity Mapping service daemon

SYNOPSIS

       /usr/lib/idmapd

DESCRIPTION

       The idmapd daemon maps Windows Security Identifiers (SIDs) to POSIX Identifiers (UIDs/GIDs) and conversely.

       The idmap(1M) utility provides a front end to the idmapd daemon.

FILES

       /var/idmap/idmap.db

	   Database  in  which	to  store  local name-based ID mapping rules. The contents of the database are private. The database should not be
	   accessed or modified directly.

       /var/run/idmap/idmap.db

	   Database in which to cache ID mappings that are generated by ephemeral ID mapping and by name-based mapping. The contents of the  data-
	   base are private. The database should not be accessed or modified directly.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+

NOTES

       The idmapd service is managed by the service management facility (SMF). The service identifier for the idmapd service is svc:/system/idmap.

       Use  the  svcadm  command  to perform administrative actions on this service, such as enabling, disabling, or restarting the service. These
       actions require the solaris.smf.manage.idmap authorization. Use the svcs command to query the service's status.

       The functionality of this daemon might change in a future release of the Solaris operating system.
