[Samba] Is it possible to 'getfacl' on a mounted samba share ?
Answering to Rowland and Louis, . I downgraded the Linux version to: p at linte> uname -a Linux linte 4.19.0-12-amd64 #1 SMP Debian 4.19.152-1 (2020-10-18) x86_64 GNU/Linux => That did not affect the outcome of 'getfacl' nor 'ls -l' . I run the proposed script, I made only a small change, "Administrator" with my default admin name in the code. ================================================================================================================= samba-collect-debug-info.sh ======================================================================================================================= Collected config? --- 2021-01-25-11:27 ----------- Hostname: linte DNS Domain: borghi.lan FQDN: linte.borghi.lan ipaddress: 172.16.3.37 ----------- Kerberos SRV _kerberos._tcp.borghi.lan record verified ok, sample output: Server:???????? 172.16.3.51 Address:??????? 172.16.3.51#53 Non-authoritative answer: *** Can't find _kerberos._tcp.borghi.lan: No answer Authoritative answers can be found from: borghi.lan ??????? origin = borghi.lan.borghi.lan ??????? mail addr = root.borghi.lan.borghi.lan ??????? serial = 2020121500 ??????? refresh = 3600 ??????? retry = 900 ??????? expire = 604800 ??????? minimum = 86400 Samba is running as a Unix domain member ----------- ??????
