<html>Hi All,<br /><br />Just an FYI, I have now added Yunolan to Winadmin, following a request on #ucc - "Any chance I can get local admin on the UCC PC's? Ive bugged Cormac 5 times today while installing node".<br />[BLU] and [BRD] also confirmed this was okay, before I made the change.<br /><br />In terms of how I did this, I deliberately did <em><u><strong>not</strong></u></em> log into Samson as `root` and use ye old `samba-tool` cowboy method.<br />Instead, I went with the much more painful (but secure) approach of using LDAP with `ldapsearch` and `ldapodify` - authenticated as me via kerberos - to update the member list of `winadmin`.<br /><br />Steps to do this as follows:<ul><li>Get a Kerberos (ticket-generating-)ticket (TGT), if you don't already have one:<ul><li>Run `klist` to see what kerberos tickets you currently possess.</li><li>Run `kinit` to get a fresh TGT.</li></ul></li><li>Get distinguished name (dn) of the target group:<ul><li>Query: `ldapsearch -H 'ldap://ad.ucc.gu.uwa.edu.au' '(sAMAccountName=winadmin)' dn`</li><li>Result: "CN=winadmin,OU=Groups,DC=ad,DC=ucc,DC=gu,DC=uwa,DC=edu,DC=au"</li></ul></li><li>Get dn of target user:<ul><li>Query: `ldapsearch -H 'ldap://ad.ucc.gu.uwa.edu.au' '(sAMAccountName=yunolan)' dn`</li><li>Result: "CN=yunolan,CN=Users,DC=ad,DC=ucc,DC=gu,DC=uwa,DC=edu,DC=au"</li></ul></li><li>Write an LDIF (script?) to add Yunolan as a member, e.g. "~/add-yunolan-to-winadmin.ldif", using the below format (see `man ldif`):<br />```<br /><em>dn: CN=winadmin,OU=Groups,DC=ad,DC=ucc,DC=gu,DC=uwa,DC=edu,DC=au<br />changetype: modify<br />add: member<br />member: CN=yunolan,CN=Users,DC=ad,DC=ucc,DC=gu,DC=uwa,DC=edu,DC=au</em><br />```</li><li>Modify the "winadmin" group with the above LDIF script:<ul><li>`ldapmodify -H 'ldap://ad.ucc.gu.uwa.edu.au' -f add-yunolan-to-winadmin.ldif`</li></ul></li><li>Check that Yunolan now shows as a member:<ul><li>LDAP Query: `ldapsearch -H 'ldap://ad.ucc.gu.uwa.edu.au' '(sAMAccountName=winadmin)' | less`</li><li>AD integration on Motsudo:<ul><li>Run: `id yunolan`</li><li>If "winadmin" doesn't show up, clear the cached AD info SSSD has on Yunolan with `sudo sss_cache -u yunolan`</li><li>Run `id yunolan` again</li></ul></li></ul></li></ul><br />Is this harder? Yes... but only because the `ldap(search|modify)` tooling kinda sucks - there are better tools out there that let you run things like `Add-ADGroupMember -Identity winadmin -Members yunolan` and call it a day, but that particular example doesn't work with SAMBA (it needs Active Directory Web Services >:( ).<br />in either case, I'd say this is a better and much more secure practice than running `samba-tool` as root on Samson.<br /><br />--<br />Kind regards,<br />Dylan Hicks [333]</html>
