[Samba] Samba-4.10.4 strange behaviour

[Strahil Nikolov]

Hello All,

I'm new to the list and I don't have much of experience with samba.

I have a test setup on CentOS 7.8 with samba-4.10.4 and samba-vfs-glusterfs .
When my client mounts the samba share via vers=1.0 , the user sees the share properly (uid,gid,mode are just like on gluster). When the share is mounted with vers=2.0 or not specified (anything higher) the files are owned by root/root and can't be changed (even by root).

Here is a short summary:

Packages:
samba-4.10.4-11.el7_8.x86_64
samba-client-libs-4.10.4-11.el7_8.x86_64
samba-common-4.10.4-11.el7_8.noarch
samba-common-libs-4.10.4-11.el7_8.x86_64
samba-common-tools-4.10.4-11.el7_8.x86_64
samba-libs-4.10.4-11.el7_8.x86_64
samba-vfs-glusterfs-4.10.4-11.el7_8.x86_64

I'm pretty sure I'm missing something , but I have no idea what it is. Any ideas why the share is viewable as "root" will be highly appreciated.


Thanks in advance.
