samba - Jul 2016 - IDMAP Issue

Good Day All,

We have an issue where the following in smb.conf :

idmap uid = 10000-20000

... it is resulting in assigned id's clashing with id's in passwd. What
are
the repercussions should we change to say the following :

idmap uid = 20000-30000

Many thanks.

Regards

Shaun

What version of Samba ?
idmap uid (and gid) are depreciated in later versions of Samba, it may 
help if you post the entire [global] section of your smb.conf.

What ever the version of Samba, raising the lower level wouldn't really 
be a good idea, any saved files belonging to an ID in the range 
10000-20000 would lose their owners.

... as follows :

rpm -qa | grep samba
samba-3.6.23-35.el6_8.x86_64
samba-common-3.6.23-35.el6_8.x86_64
samba-winbind-clients-3.6.23-35.el6_8.x86_64
samba-winbind-3.6.23-35.el6_8.x86_64

[global]
    workgroup = ABC
    realm = ABC.COM
    security = ADS
    restrict anonymous = 1
    log file = /var/log/samba/log.%m
    max log size = 50
    client signing = required
    server signing = Yes
    socket options = TCP_NODELAY SO_RCVBUF=16384 SO_SNDBUF=16384
    dns proxy = No
    wins server = x.x.x.x
    socket address = x.x.x.x
    winbind separator = +
    winbind enum users = Yes
    winbind enum groups = Yes
    idmap config * : range = 10000-20000
    idmap config * : backend = tdb
