Dear sssd users,
I would like to get informations about the use of sssd with samba (centos 7,
I need it because I configured a samba share, accessible with sssd.
The authentication is against a windows AD.
My /etc/nsswitch.cnf is configured only with sssd :
/passwd: files sss//
//shadow: files sss//
//group: files sss/
For an other purpose, I set an sftpd access also configured with sssd
against the AD.
I followed some discussions on the samba user list about samba + sssd.
I would like to understand if there are some issues with sssd and samba
4.8.3 on centos 7 ?
Or is it with next RHEL 8 ?
/The RHEL 8 documentation states this: //
//"Red Hat only supports running Samba as a server with the winbindd //
//service to provide domain users and groups to the local system. Due to //
//certain limitations, such as missing Windows access control list (ACL) //
//support and NT LAN Manager (NTLM) fallback, SSSD is not supported." //
//What's confusing is that the RHEL 7 documentation says: //
//"Prior to Red Hat Enterprise Linux 7.1, only Winbind provided this //
//functionality. In Red Hat Enterprise Linux 7.1 and later, you no longer //

//"4.2.2. Determining Whether to Use SSSD or Winbind for SMB Shares //

//"In environments with direct Active Directory integration where the //

In my case, running samba 4.8.3 with SSSD on centos 7 do I need to :
I'm not an expert in this are, but look at some threads in the list
archive e.g. this one:
even has a full example.
- enable and start winbind service , in conjunction to sssd ?
Yes, that's my understanding with recent Samba releases
- or only sssd is enough with samba ?
- Do I have to fear issues in next release of sssd for the support of samba
? especially for acls support ?/
A nsswitch.conf like :
passwd: files sss winbind
shadow: files sss winbind
group: files sss winbind
..but I don't think you need the NSS maps enabled, IIRC just the service
must be running..
passwd: files winbind sss
shadow: files winbind sss
group: files winbind sss
Does not seem to work... I test and this is not stable.
