yeah, I figured out id was outputting the "no such user" to stderr just a moment ago.

Your suggestion worked brilliantly.

Thanks!

Incase anyone's interested, here's the "draft 1". It could be streamlined more, and I also plan to add the ability to delete members, and maybe compare the group against the input, and only add/remove those users that differ.

Feel free to use, though, I doubt it's worth much to people other than myself. =)

Code:
#!/bin/bash

#This script will take two arguments, the group name, and the user list. 
#It is recommended that the group be cleared before running this script since
#it will not remove people from the group.

dirnode="/LDAPv3/ldap.example.com"

if [ "$#" != "2" ]; then
echo -e "Usage of the groupadd script: $0 groupname userlist\n"
exit 1
else


echo "The following users do not exist in the directory" > ./non_existant_users.txt
group="$1"
userlist="$2"

echo "Adding users in $userlist to group $group"

read -p 'Enter username with directory write : ' admin
read -p 'Enter password for user : ' -s password

#echo "test user: $admin, test pass: $password"
echo "group: $group, userlist: $userlist"

for user in `cat $userlist`; do
	if ! id -u "$user" >/dev/null 2>&1; then
		echo "User $user does not exist!"
		non_existant="$non_existant $user"
	else
		exists="$exists $user"
	fi
done

for isuser in $exists; do
	#dseditgroup -o checkmember -m $isuser $group
	dseditgroup -o edit -n $dirnode -u $admin -P $password -a $isuser -t user $group
done

for nonuser in $non_existant; do
	echo $nonuser >> ./non_existant_users.txt
done

fi

DESCRIPTION

     dseditgroup allows manipulation of a single named group record on either the default local node or the specified DirectoryService node. For
     the "read" operation the authentication search policy (/Search node) is consulted. Default behaviour is presented below after a discussion of
     each operation and the possible parameters.

     Options and their descriptions:

     -o operation
	      If "read" then the parameters of the specified groupname will be displayed. This is the default option. The authentication search
	      policy (/Search node) will be used.

	      If "create" then create a group with the specified groupname on either the default local node or the specified DirectoryService
	      node.

	      If "delete" then delete a group with the specified groupname on either the default local node or the specified DirectoryService
	      node.

	      If "edit" then edit a group with the specified groupname on either the default local node or the specified DirectoryService node.

	      If "checkmember" then check if the user specified with -m or current logged in user is a member of the specified groupname. The
	      authentication search policy (/Search node) is used to find the member. The specified node (defaults to the authentication search
	      policy) is used to find the group. If the specified node is not on the authentication search policy the behaviour is undefined.

     -p       You will be prompted for a password to use in conjunction with the specified username.

     -q       This disables interactive verification of replace or delete operations.

     -v       This enables the logging of the DirectoryService API calls and their return codes.

     Parameters and their descriptions:

     -m member
	      The username of the account to verify group membership when using -o checkmember

     -n nodename
	      Directory Service node name such as /LDAPv3/ldap.company.com and whose default value is the local node. "." can also be used to
	      specify the local node.

     -u username
	      Username of a user that has administrative privileges on this computer.

     -P password
	      Password to use in conjunction with the specified username.  If this is not specified, you will be prompted for a password.

     -a recordname
	      The name of the record to be added to the group specified by groupname. This name is related to the first record found on the
	      authentication search policy when a search is made with this recordname and the given recordtype.

     -d recordname
	      The name of the record to be deleted from the group specified by groupname. This name is related to the first record found on the
	      authentication search policy when a search is made with this recordname and the given recordtype.

     -t recordtype
	      The type of the record to be added to or deleted from the group specified by groupname. Valid values are user, computer, group, or
	      computergroup.

     -T grouptype
	      The type of the group record to be created or modified as specified by groupname. Valid values are group or computergroup.

     -L       If used with computergroup will also maintain the computerlist if it exists or create it if a computergroup is created.

     -i gid   This is a group id. This will be automatically created if not specified for a create.

     -g guid  This is a text representation of an 128 bit id. This will be automatically created if not specified for a create.

     -r realname
	      This is a simple text string.

     -k keyword
	      This is a simple text string.

     -c comment
	      This is a simple text string.

     -s timetolive
	      The number of seconds that this record is deemed valid as a cached value. There will be no automatically created default value if
	      not specified for a create.

DEFAULT BEHAVIOUR

     dseditgroup mygroup

     This simple version of the command will default to:

     dseditgroup -o read -n . -u $USER mygroup

     The output will be the parameters of the "mygroup" group record if the shell user has read access to the local node's group record of name
     "mygroup".

EXAMPLES

     dseditgroup extragroup

     dseditgroup -o read extragroup

		    The attributes of the group extragroup from the local node are displayed.

     dseditgroup -o create -n /LDAPv3/ldap.company.com -u myusername -P mypassword -r "Extra Group" -c "a nice comment" -s 3600 -k "some keyword"
	      extragroup

		    The group extragroup is created from the node /LDAPv3/ldap.company.com with the realname, comment, timetolive (instead of
		    default of 14400 = 4 hours), and keyword atttribute values given above if the user myusername has supplied a correct password
		    and has write access.

     dseditgroup -o delete -n /LDAPv3/ldap.company.com -u myusername -P mypassword extragroup

		    The group extragroup is deleted from the node /LDAPv3/ldap.company.com if the user myusername has supplied a correct password
		    and has write access.

     dseditgroup -o edit -n /LDAPv3/ldap.company.com -u myusername -p -a username -t user extragroup

		    The group extragroup from the node /LDAPv3/ldap.company.com will have the username added if the username is in a user record
		    on the search policy and if the correct password is presented interactively for the user myusername which also need to have
		    write access.

     dseditgroup -o edit -n /LDAPv3/ldap.company.com -u myusername -P -a mysubgroup -t group extragroup

		    The group extragroup from the node /LDAPv3/ldap.company.com will have the mysubgroup added if the mysubgroup is in a group
		    record on the search policy and if the user myusername has supplied a correct password and has write access.

     dseditgroup -o edit -n /LDAPv3/ldap.company.com -u myusername -p -d username -t user extragroup

		    The group extragroup from the node /LDAPv3/ldap.company.com will have the username deleted if the correct password is
		    presented interactively for the user myusername which also need to have write access.

     dseditgroup -o checkmember extragroup

		    Will write out a message specifying if the current user is a member of extragroup on the authentication search policy.

     dseditgroup -o checkmember -n  . extragroup

		    Will write out a message specifying if the current user is a member of extragroup on the local node.

     dseditgroup -n /LDAPv3/ldap.company.com -o checkmember -m user extragroup

		    Will write out a message specifying if user (found in /Search) is a member of extragroup on the specified node
		    /LDAPv3/ldap.company.com. The specified node /LDAPv3/ldap.company.com needs to be on the authentication search policy for a
		    valid answer.
