Maybe its.. authconfig --enablewinbindkrb5 --update Requirements to achieve this: - A valid /etc/krb5.conf - A valid system keytab /etc/krb5.keytab - A valid /etc/samba/smb.conf -> will be modified by authconfig ( found on internet worked in centos7 ) But better read.. https://sssd.io/docs/users/pam_krb5_migration.html Greetz, Louis > -----Oorspronkelijk bericht----- >

Absolutely.? In fact,? both systems are using the identical smb.conf,

I'm experimenting with smb + winbind. My host is joined to AD and I can login to my host fine using my AD credentials via SSH.?? The only issue is that I don't get a Kerberos ticket generated. In /etc/security/pam_winbind.conf I have: krb5_auth = yes krb5_ccache_type = KEYRING In /etc/krb5.conf, I also have: default_ccache_name = KEYRING:persistent:%{uid} Using wbinfo -K jas, then

We are using tmux, screen and x2go to run long-running jobs on our compute servers. $HOME and other data should be mounted via CIFS or NFS4. Because such a job can run for more than a week, I would like to increase the Kerberos ticket lifetime or better the Kerberos ticket maximum renewable lifetime. I found this guide: https://wiki.samba.org/index.php/Samba_KDC_Settings Unfortunately, only

Hi list,I want to make winbind kerberos ticket refresh work but I couldn't do it with configuration below: ------ smb.conf ------security = ADS workgroup = MYDOMAINrealm = MYDOMAIN.ORG log file = /var/log/samba/%m.loglog level = 6enable core files = no idmap config * : backend = tdbidmap config * : range = 3000-7999idmap config MYDOMAIN : backend = rid idmap config MYDOMAIN : range =
