-{{OODNotice}}
-Group accounts are necessary when a number of users need access to the same set of files, for example, a society webpage. All of the users who wish to edit these files **MUST** be tardis account holders.
-Two things need set up, the group (or role) account, and the the unix group. Both will have the same name.
-====== Creating the group/role account ======
-===== Add normal user account =====
-Use ''tardis adduser <username>'' add an account.
-===== Removing the account password =====
-Create a file called ''removepw.ldif'' (or use the one on ''vortis:/root/'').
-  # extended LDIF
-  #
-  # LDAPv3
-  # base <ou=Group,dc=tardis,dc=ed,dc=ac,dc=uk> with scope sub
-  # filter: cn=admin
-  # requesting: ALL
-  #
-  #
-  # Use ldapmodify, bound as root or as the user
-  dn: uid=GROUPNAME,ou=People,dc=tardis,dc=ed,dc=ac,dc=uk
-  changetype: modify
-  replace: userPassword
-  userPassword:
-Then do:
-  ldapmodify -x -D cn=admin,dc=tardis,dc=ed,dc=ac,dc=uk -W -f removepw.ldif
-====== Creating the group ======
-===== Get a group ID =====
-  ldapsearch -x -b 'ou=Group,dc=tardis,dc=ed,dc=ac,dc=uk' objectClass=posixGroup
-Pick a new one that's one higher than the previous highest one, etc.
-===== Create the group =====
-Create a file (or use the one in ''vortis:/root/''), substituting the capitalised bits with the appropriate information:
-  # GROUPNAME, Group, tardis.ed.ac.uk
-  dn: cn=GROUPNAME,ou=Group,dc=tardis,dc=ed,dc=ac,dc=uk
-  objectClass: posixGroup
-  objectClass: top
-  cn: GROUPNAME
-  gidNumber: GROUPNUMBER
-  memberUid: SOMEUSER
-//Does the memberUid entry need to be there when creating? Probably not, but you'll know at least one user to put in the group when you make the account, and it saves you messing with ldapvi later//
-Save it as ''addgroup.ldif'', then do:
-  ldapadd -x -D cn=admin,dc=tardis,dc=ed,dc=ac,dc=uk -W -f addgroup.ldif
-This needs the LDAP admin password.
-====== Adding users to the group ======
-Using ldapvi:
-  ldapvi -h ldap.tardis.ed.ac.uk -D 'cn=admin,dc=tardis,dc=ed,dc=ac,dc=uk' -b 'ou=Group,dc=tardis,dc=ed,dc=ac,dc=uk' '(cn=GROUPNAME)'
-//(substituting the relevant group name for GROUPNAME//)
-You will be presented with vim, looking a bit like:
-  # ldapvi(1)
-cn=gliding,ou=Group,dc=tardis,dc=ed,dc=ac,dc=uk
-  objectClass: posixGroup
-  objectClass: top
-  cn: GROUPNAME
-  userPassword: {crypt}*
-  gidNumber: GROUPNUMBER
-  memberUid: SOMEMEMBER
-Add memberUid entries at the bottom for each for each user required.
-Save the file and quit vim, and the groups will be updated.
-====== Allowing sudo access ======
-Allow the users to su to the role account by editing /etc/sudoers appropriately using visudo.
-====== Creating group webspace ======
-//Same as user webspace, with obvious changes//.
-See [[general_administration#Providing_a_user_with_web_space|General Administration]].
-====== Adding a vhost ======
-There are two ways to add vhosts. One for fussy people and one for lazy people.
-The lazy option is to simply add the appropriate CNAME for www in DNS. Then requests aimed at http://www.foo.tardis.ed.ac.uk/ are proxied to http://www.tardis.ed.ac.uk/~foo/
-Fussy people (with scripts that care that the user's seeing the same url the script thinks they're seeing) need the above done, as well as:
-  * An entry in davros:/etc/apache/vhosts/foo . Have a poke around at others in there to look for one that's close to what you want, the etv one looks fairly minimal. Oh, and remember to use [[rcs]]!
-  * Directories and things in /tardis/www/vhosts/foo/ . Use the same structure here as for single users.
-====== Usage ======
-Advise your group account users to then use "sudo -u <groupaccountname> -s -H" to use the account.
