[Samba] Samba Fatal Error: GID range full!! (max: 20000)

A couple of obvious questions:  

I'm going to assume you've restarted winbindd and smbd, but I thought
I'd mention it because I've done similarly dumb things.

How many users/groups are you enumerating into winbind?  It seems like
unless you're on a huge domain, you're not going to have 20000.  wbinfo
-u | wc -l will tell you how many mappings it has currently.  If it's a
large number, say 20000, you may need to set winbind enum users = no
(and likewise for groups)

Does the new range overlap the previous working range?  If not, is it
possible you've orphaned the uids and gids in the old range?  I haven't
looked at the winbind code, that's purely speculative, but it's
something to try while somebody more authoritative mulls over your

I have set large, non-overlapping ranges for idmap uid and gid.

Although the error messages about the GID range are no longer seen,
users still cannot access their shares.

Only changes from the working smb.conf from yesterday are the reset
idmap ranges and the debug level setting.

workgroup = JJS-SDM
netbios name = appian
server string = appian
hosts allow = 192.168.1. 127.
log file = /var/log/samba/%m.log
debug level = 5
max log size = 50
security = user
encrypt passwords =  no
unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n
winbind separator = +
idmap uid = 100000-300000
idmap gid = 100000-300000
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = yes
template homedir = /home/winnt/%D/%U
template shell = /bin/bash
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 local master
= no domain master = no preferred master = no domain logons = no wins
server = dns proxy = no
