Re: [Samba] Setup of Samba with Solaris 11.3 to provide Unix File Shares to Windows Users




Thanks Rowland and Louis,

after changing from ad to rid, i get all users listed with "getent passwd",
not just the ones with uidNumber - which is good. But "getent passwd
MYDOM\\mdecker" still does not resolve. In addition, no groups are listed
with "getent group". Looking at winbindd debug, it seems that after trying
getgrsid on the very first group "Exchange  All Hosted Organizations", it
stops to retrieve other groups.

       out: struct wbint_QueryGroupList
            groups                   : *
                groups: struct wbint_Principals
                    num_principals           : 545
                    principals: ARRAY(545)
                        principals: struct wbint_Principal
                            sid                      :
S-1-5-21-1585417398-3384821309-2524188735-2571
                            type                     : SID_NAME_DOM_GRP (2)
                            name                     : *
                                name                     : 'Exchange All
Hosted Organizations'

Authentication on windows to access share (connect network drive) is still
not possible.

getpwnam MDECKER

Could not convert sid S-0-0: NT_STATUS_NO_SUCH_USER

Authentication with "kinit@xxxxxxxxx" is working.

This is after "net cache flush" and restarting winbind and samba multiple
times....

Best regards,
Martin
