I've managed to work past the WARNINGS, by inserting the following code into Line 73 of '/usr/sbin/lat-users'.
ORIGINAL Code:
"Street", $fields[6],
MODIFIED Code:
"Shell", "/usr/bin/rssh",
"VPNClientAccess", "no",
"Street", $fields[6],
** PLEASE NOTE: When updating users with 'lat-users' the 'Uid' is changed in '/home/e-smith/db/accounts'. I don't think this is supposed to happen (Uid is not changed, when using Server-Manger), so I would only suggest using 'lat-users' to create users, at this time. Also... 'lat-users' does not create the default 'firstname.lastname' and 'firstname_lastname' pseudonyms, like Server-Manager does, during the user creation process. To create the default pseudonyms, you will either need to run the 'lat-pseudonyms' script, or click 'Modify' and 'Save' on every user in Server-Manager.
