            Bug ID: 210591
           Summary: nscd bug: no caching for supplementary groups from
                    ldap
           Product: Base System
           Version: 10.2-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: ilyushkeane at gmail.com

I found strange nscd behavior, which I assume is a bug. I've already request
help of initial maintainer directly (as it noted in man), but unfortunately he
is not an active maintainer (which I also request as #210590). Also I've found,
that current development of nscd is barely active, and that's why I suppose
10.2-STABLE is no reason to discard this request.

Prerequisites are the following:
- FreeBSD 10.2-STABLE-r286912
- /etc/nscd.conf:
enable-cache passwd yes
enable-cache group yes
enable-cache hosts yes
enable-cache services yes
enable-cache protocols yes
enable-cache rpc yes
enable-cache networks yes

We have an ldap installation and everything works fine, but there is no caching
for supplementary groups. For example:

(nscd restarted, ldap is after files in /etc/nsswitch.conf)
[root at serv /]# id -Gn user
user dns
(ldap commented out in /etc/nsswitch.conf)
[root at serv /]# id -Gn user
user

Also I tried to make use of following /etc/nscd.conf options (but they didn't
work out):

threads 1
enable-cache passwd_compat yes
enable-cache group_compat yes

Google doesn't have any information about this behaviour, please check if there
is something you can do.
Thanks.
