Can't sudo Using Group Permission
All:
I'm having a problem with sudo on Solaris 5.10 that is giving me fits (and BTW, I'm a Linux admin by trade...).
The issue is that I have a number of users (myself included) that cannot sudo to root to complete user admin tasks. Assuming the user is jdoe, and the group with the elevated permissions is called useradmins, here is what the configurations look like (sorry - had to change the details due to confidentiality stuff...):
/etc/passwd entry:
jdoe:x:26199:26199::/home/jdoe:/usr/bin/bash
/etc/group entries:
useradmins::15:user1,user2,user3,user4,user5,user6,user7
useradmins::15:user8,user9,jdoe,user10
jdoe::26199:
Relevant section of /usr/local/etc/sudoers
# All unix users in the sysadmin group get to run what eveah
%useradmins ALL=(ALL) ALL
And some command line fun and games:
[root@solbox ~]# id jdoe
uid=26199(jdoe) gid=26199(jdoe)
[root@solbox ~]# groups jdoe
jdoe useradmins
Some things of interest...
> Yes, there are two useradmins groups, both with the same gid. I found some postings from the Google that reference a line-length limit, and that some people have overcome this by creating a second entry for the group. We're at roughly 260 chars on the first line of the file, so I'm not sure why there are two entries.
> I suspect the issue surrounds the id and groups commands. groups shows me as a member of my own personal group, as well as a member of the useradmins group. id, on the other hand shows no useradmins membership.
> When I tried a truss -f id jdoe, I don't see anything in the output that leads me to see anything returning an error code. There are numerous door_info and door_call calls which are a complete enigma to me, but each returns a 0 (presumably, success?)
Any help is appreciated.

dscacheutil(1) BSD General Commands Manual dscacheutil(1)
NAME
dscacheutil -- gather information, statistics and initiate queries to the Directory Service cache.
SYNOPSIS
dscacheutil -h
dscacheutil -q category [-a key value]
dscacheutil -cachedump [-buckets] [-entries [category]]
dscacheutil -configuration
dscacheutil -flushcache
dscacheutil -statistics
DESCRIPTION
dscacheutil does various operations against the Directory Service cache including gathering statistics, initiating lookups, inspection, cache
flush, etc. This tool replaces most of the functionality of the lookupd tool previously available in the OS.
FLAGS
A list of flags and their descriptions:
-h Lists the options for calling dscacheutil
-q category
Initiate a query using standard calls. These calls will either return results from the cache or go fetch live data and place them in
the cache. By default if no specific query is requested via -a then all results within that category will be returned.
-a key value
Optional flag to -q for a specific key with a value.
-cachedump
Dumps an overview of the cache by default. Additional flags will provide more detailed information.
-buckets
Used in conjunction with -cachedump to also print hash bucket usage of the current cache.
-entries [category]
Used in conjunction with -cachedump to dump detailed information about cache entries. An optional category can be supplied to only
see types of interest. Dumping 'host' entries can only be done by administrative users.
-configuration
Prints current configuration information, such as the search policy from Directory Service and cache parameters.
-flushcache
Flushes the entire cache. This should only be used in extreme cases. Validation information is used within the cache along with
other techniques to ensure the OS has valid information available to it.
-statistics
Prints statistics from the cache including an overview and detailed call statistics. Some calls are not cached but are derived from
other calls internally. Cache hits and cache misses may not always be equal to external calls. For example getaddrinfo is actually
a combination of gethostbyname with other calls internally to the cache to maximize cache hit rate.
Available categories and associated keys:
group name or gid
host name or ip_address (used for both IPv6 and IPv4)
mount name
protocol name or number
rpc name or number
service name or port
user name or uid
EXAMPLES
Lookup a user:
% dscacheutil -q user -a name jdoe
name: jdoe
password: ********
uid: 501
gid: 501
dir: /Users/jdoe
shell: /bin/csh
gecos: John Doe
Lookup all users:
% dscacheutil -q user
Dump cache overview:
% dscacheutil -cachedump
Dump cache details with user entries:
% dscacheutil -cachedump -entries user
