If you use [homes] (without the path), the Unix home directory is set to the 6th section of 'getent passwd username' and can be something like '/home/username'. This is set by Samba in one of two ways for an AD unix user, either by using the 'ad' backend which will extract the users 'unixHomeDirectory' attribute from AD, or by setting 'template homedir' in smb.conf.> >> How did you create the domain ? > Following the guide [2] > samba-tool domain provision --server-role=dc --use-rfc2307 --dns-backend=BIND9_DLZ --realm=WDC.MYDOMAIN.IT --domain=WDC --adminpass=passworNothing wrong there.>> Oh Dear, you seem to have a kerberos server running on your Samba AD DC, >> no sorry, make that two kerberos servers. > Well, it's NOT running. > Anyway I didn't install it on purpose, if it's there it came as a dependency of something else (Ubuntu.You posted: Cannot open DB2 database '/etc/krb5kdc/principal' I would expect to only see that on a machine with the MIT kdc installed, try this apt-get -s remove krb5-kdc This will prove one way or other if it is installed and what it wants to remove along with it, it will not remove anything.> >> That is unless your OS is Fedora and you are using the distro packages >> and you missed the 'experimental' warning. > Which warning are you referring to?

The following packages will be REMOVED: krb5-kdc 0 upgraded, 0 newly installed, 1 to remove and 21 not upgraded. Remv krb5-kdc [1.16-2ubuntu0.1] I checked in apt history log and the package was installed manually, it's in the "Verified package dependencies" script for Ubuntu 18.04 [1] [1] https://wiki.samba.org/index.php/Package_Dependencies_Required_to_Build_Samba#Verified_Package_Dependencies -- Lorenzo Milesi - lorenzo.milesi at yetopen.it YetOpen S.r.l. - https://www.yetopen.it/ Via Salerno 18 - 23900 Lecco - ITALY - Tel +39 0341 220 205 - Fax +39 178 6070 222 Think green - Non stampare questa e-mail se non necessario / Don't print this email unless necessary -------- D.Lgs. 196/2003 e GDPR 679/2016 -------- Tutte le informazioni contenute in questo messaggio sono riservate ed a uso esclusivo del destinatario.
