root@dlp:~#
vi /etc/sssd/sssd.conf # line 16 : change use_fully_qualified_names = False
root@dlp:~#
root@dlp:~# systemctl restart sssd id Administrator uid=1109000500(administrator) gid=1109000513(domain users) groups=1109000513(domain users),1109000520(group policy creator owners),1109000518(schema admins),1109000512(domain admins),1109000519(enterprise admins),1109000572(denied rodc password replication group) |

AD users UID/GID are asigned randomly, but if you'd like to assign fixed UID/GID, configure like follows.
Add UNIX attributes to AD accounts first, refer to here ([2] and later).
Next, change SSSD settings on Debian Server.
This example is based on the environment AD accounts have [uidNumber/gidNumber] attributes. |

root@dlp:~#
vi /etc/sssd/sssd.conf # line 17 : change ldap_id_mapping = False
# add to the end ldap_user_uid_number = uidNumber ldap_user_gid_number = gidNumber # clear cache and restart sssd root@dlp:~# rm -f /var/lib/sss/db/* root@dlp:~# systemctl restart sssd
id serverworld uid=5000(serverworld) gid=5000 groups=5000 |
