++
++purposes of this patch:
++
++This patch would help to have authentication centralization policy
++using ssh public key authentication.
++This patch could be an alternative to other "secure" authentication system
++working in a similar way (Kerberos, SecurID, etc...), except the fact
++that it's based on OpenSSH and its public key abilities.
++
++>> FYI: <<
++'uid': means unix accounts existing on the current server
++'lpkServerGroup:' mean server group configured on the current server ('lpkServerGroup' in sshd_config)
++
++example schema:
++
++
++ server1 (uid: eau,rival,toto) (lpkServerGroup: unix)
++ ___________ /
++ / \ --- - server3 (uid: eau, titi) (lpkServerGroup: unix)
++ | LDAP Server | \
++ | eau ,rival | server2 (uid: rival, eau) (lpkServerGroup: unix)
++ | titi ,toto |
++ | userx,.... | server5 (uid: eau) (lpkServerGroup: mail)
++ \___________/ \ /
++ ----- - server4 (uid: eau, rival) (no group configured)
++ \
++ etc...
++
++- WHAT WE NEED :
++
++ * configured LDAP server somewhere on the network (i.e. OpenLDAP)
++ * patched sshd (with this patch ;)
++ * LDAP user(/group) entry (look at users.ldif (& groups.ldif)):
++ User entry:
++ - attached to the 'ldapPublicKey' objectclass
++ - attached to the 'posixAccount' objectclass
++ - with a filled 'sshPublicKey' attribute
++ Example:
++ dn: uid=eau,ou=users,dc=cuckoos,dc=net
++ objectclass: top
++ objectclass: person
++ objectclass: organizationalPerson
++ objectclass: posixAccount
++ objectclass: ldapPublicKey
++ description: Eric AUGE Account
++ userPassword: blah
++ cn: Eric AUGE
++ sn: Eric AUGE
++ uid: eau
++ uidNumber: 1034
++ gidNumber: 1
++ homeDirectory: /export/home/eau
++ sshPublicKey: ssh-dss AAAAB3...
++ sshPublicKey: ssh-dss AAAAM5...
++
++ Group entry:
++ - attached to the 'posixGroup' objectclass
++ - with a 'cn' groupname attribute
++ - with multiple 'memberUid' attributes filled with usernames allowed in this group
++ Example:
++ # few members
++ dn: cn=unix,ou=groups,dc=cuckoos,dc=net
++ objectclass: top
++ objectclass: posixGroup
++ description: Unix based servers group
++ cn: unix
++ gidNumber: 1002
++ memberUid: eau
++ memberUid: user1
++ memberUid: user2
++
++
++- HOW IT WORKS :
++
++ * without patch
++ If a user wants to authenticate to log in a server the sshd, will first look for authentication method allowed (RSAauth,kerberos,etc..)
++ and if RSAauth and tickets based auth fails, it will fallback to standard password authentication (if enabled).
++
++ * with the patch
++ If a user want to authenticate to log in a server, the sshd will first look for auth method including LDAP pubkey, if the ldappubkey options is enabled.
++ It will do an ldapsearch to get the public key directly from the LDAP instead of reading it from the server filesystem.
++ (usually in $HOME/.ssh/authorized_keys)
++
++ If groups are enabled, it will also check if the user that wants to login is in the group of the server he is trying to log into.
++ If it fails, it falls back on RSA auth files ($HOME/.ssh/authorized_keys), etc.. and finally to standard password authentication (if enabled).
++
++ 7 tokens are added to sshd_config :
++ # here is the new patched ldap related tokens
++ # entries in your LDAP must be posixAccount & strongAuthenticationUser & posixGroup
++ UseLPK yes # look the pub key into LDAP
++ LpkServers ldap://10.31.32.5/ ldap://10.31.32.4 ldap://10.31.32.3 # which LDAP server for users ? (URL format)
++ LpkUserDN ou=users,dc=foobar,dc=net # which base DN for users ?
++ LpkGroupDN ou=groups,dc=foobar,dc=net # which base DN for groups ?
++ LpkBindDN cn=manager,dc=foobar,dc=net # which bind DN ?
++ LpkBindPw asecret # bind DN credidentials
++ LpkServerGroup agroupname # the group the server is part of
++
++ Right now i'm using anonymous binding to get public keys, because getting public keys of someone doesn't impersonate him¸ but there is some
++ flaws you have to take care of.
++
++- HOW TO INSERT A USER/KEY INTO AN LDAP ENTRY
++
++ * my way (there is plenty :)
++ - create ldif file (i.e. users.ldif)
++ - cat ~/.ssh/id_dsa.pub OR cat ~/.ssh/id_rsa.pub OR cat ~/.ssh/identity.pub
++ - my way in 4 steps :
++ Example:
++
++ # you add this to the user entry in the LDIF file :
++ [...]
++ objectclass: posixAccount
++ objectclass: ldapPublicKey
++ [...]
++ sshPubliKey: ssh-dss AAAABDh12DDUR2...
++ [...]
++
++ # insert your entry and you're done :)
++ ldapadd -D balblabla -w bleh < file.ldif
++
++ all standard options can be present in the 'sshPublicKey' attribute.
++
++- WHY :
++
++ Simply because, i was looking for a way to centralize all sysadmins authentication, easily, without completely using LDAP
++ as authentication method (like pam_ldap etc..).
++
++ After looking into Kerberos, SecurID, and other centralized secure authentications systems, the use of RSA and LDAP to get
++ public key for authentication allows us to control who has access to which server (the user needs an account and to be in 'strongAuthenticationUser'
++ objectclass within LDAP and part of the group the SSH server is in).
++
++ Passwords update are no longer a nightmare for a server farm (key pair passphrase is stored on each user's box and private key is locally encrypted using his passphrase
++ so each user can change it as much as he wants).
++
++ Blocking a user account can be done directly from the LDAP (if sshd is using RSAAuth + ldap only).
++
++- RULES :
++ Entry in the LDAP server must respect 'posixAccount' and 'ldapPublicKey' which are defined in core.schema.
++ and the additionnal lpk.schema.
++
++ This patch could allow a smooth transition between standard auth (/etc/passwd) and complete LDAP based authentication
++ (pamldap, nss_ldap, etc..).
++
++ This can be an alternative to other (old?/expensive?) authentication methods (Kerberos/SecurID/..).
++
++ Referring to schema at the beginning of this file if user 'eau' is only in group 'unix'
++ 'eau' would ONLY access 'server1', 'server2', 'server3' AND 'server4' BUT NOT 'server5'.
++ If you then modify the LDAP 'mail' group entry to add 'memberUid: eau' THEN user 'eau' would be able
++ to log in 'server5' (i hope you got the idea, my english is bad :).
++
++ Each server's sshd is patched and configured to ask the public key and the group infos in the LDAP
++ server.
++ When you want to allow a new user to have access to the server parc, you just add him an account on
++ your servers, you add his public key into his entry on the LDAP server, it's done.
++
++ Because sshds are looking public keys into the LDAP directly instead of a file ($HOME/.ssh/authorized_keys).
++
++ When the user needs to change his passphrase he can do it directly from his workstation by changing
++ his own key set lock passphrase, and all servers are automatically aware.
++
++ With a CAREFUL LDAP server configuration you could allow a user to add/delete/modify his own entry himself
++ so he can add/modify/delete himself his public key when needed.
++
++ FLAWS :
++ LDAP must be well configured, getting the public key of some user is not a problem, but if anonymous LDAP
++ allow write to users dn, somebody could replace someuser's public key by its own and impersonate some
++ of your users in all your server farm be VERY CAREFUL.
++
++ MITM attack when sshd is requesting the public key, could lead to a compromise of your servers allowing login
++ as the impersonnated user.
++
++ If LDAP server is down then, fallback on passwd auth.
++
++ the ldap code part has not been well audited yet.

++
++>> FYI: <<
++Multiple 'sshPublicKey' in a user entry are allowed, as well as multiple 'memberUid' attributes in a group entry
++
++- COMPILING:
++ 1. Apply the patch
++ 2. ./configure --with-your-options --with-ldap=/prefix/to/ldap_libs_and_includes
++ 3. make
++ 4. it's done.
++
++- BLA :
++ I hope this could help, and i hope to be clear enough,, or give ideas. questions/comments/improvements are welcome.

++OpenSSH LDAP keystore Patch
++===========================
++
++NOTE: these notes are a transcript of a specific installation
++ they work for me, your specifics may be different!
++ from John Lane March 17th 2005 john@lane.uk.net
++
++This is a patch to OpenSSH 4.0p1 to allow it to obtain users' public keys
++from their LDAP record as an alternative to ~/.ssh/authorized_keys.
++
++(Assuming here that necessary build stuff is in $BUILD)
++
++cd $BUILD/openssh-4.0p1
++patch -Np1 -i $BUILD/openssh-lpk-4.0p1-0.3.patch
++mkdir -p /var/empty &&
++./configure --prefix=/usr --sysconfdir=/etc/ssh \
++ --libexecdir=/usr/sbin --with-md5-passwords --with-pam \
++ --with-libs="-lldap" --with-cppflags="-DWITH_LDAP_PUBKEY"
++Now do.
++make &&
++make install
++
++Add the following config to /etc/ssh/ssh_config
++UseLPK yes
++LpkServers ldap://myhost.mydomain.com
++LpkUserDN ou=People,dc=mydomain,dc=com
++
++We need to tell sshd about the SSL keys during boot, as root's
++environment does not exist at that time. Edit /etc/rc.d/init.d/sshd.
++Change the startup code from this:
++ echo "Starting SSH Server..."
++ loadproc /usr/sbin/sshd
++ ;;
++to this:
++ echo "Starting SSH Server..."
++ LDAPRC="/root/.ldaprc" loadproc /usr/sbin/sshd
++ ;;
++
++Re-start the sshd daemon:
++/etc/rc.d/init.d/sshd restart
++
++Install the additional LDAP schema
++cp $BUILD/openssh-lpk-0.2.schema /etc/openldap/schema/openssh.schema
++
++Now add the openSSH LDAP schema to /etc/openldap/slapd.conf:
++Add the following to the end of the existing block of schema includes
++include /etc/openldap/schema/openssh.schema
++
++Re-start the LDAP server:
++/etc/rc.d/init.d/slapd restart
++
++To add one or more public keys to a user, eg "testuser" :
++ldapsearch -x -W -Z -LLL -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
++"uid=testuser,ou=People,dc=mydomain,dc=com" > /tmp/testuser
++
++append the following to this /tmp/testuser file
++objectclass: ldapPublicKey
++sshPublicKey: ssh-rsa
++AAAAB3NzaC1yc2EAAAABJQAAAIB3dsrwqXqD7E4zYYrxwdDKBUQxKMioXy9pxFVai64kAPxjU9KS

++7eZE/gVbn2UQkQq7+kdDTS2yXV6VnC52N/kKLG3ciBkBAw== General Purpose RSA Key
++
++Then do a modify:
++ldapmodify -x -D "uid=testuser,ou=People,dc=mydomain,dc=com" -W -f
++/tmp/testuser -Z
++Enter LDAP Password:
++modifying entry "uid=testuser,ou=People,dc=mydomain,dc=com"
++And check the modify is ok:
++ldapsearch -x -W -Z -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
++"uid=testuser,ou=People,dc=mydomain,dc=com"
++Enter LDAP Password:
++# extended LDIF
++#
++# LDAPv3
++# base <uid=testuser,ou=People,dc=mydomain,dc=com> with scope sub
++# filter: (objectclass=*)
++# requesting: ALL
++#
++
++# testuser, People, mydomain.com
++dn: uid=testuser,ou=People,dc=mydomain,dc=com
++uid: testuser
++cn: testuser
++objectClass: account
++objectClass: posixAccount
++objectClass: top
++objectClass: shadowAccount
++objectClass: ldapPublicKey
++shadowLastChange: 12757
++shadowMax: 99999
++shadowWarning: 7
++loginShell: /bin/bash
++uidNumber: 9999
++gidNumber: 501
++homeDirectory: /home/testuser
++userPassword:: e1NTSEF9UDgwV1hnM1VjUDRJK0k1YnFiL1d4ZUJObXlZZ3Z3UTU=
++sshPublicKey: ssh-rsa
++AAAAB3NzaC1yc2EAAAABJQAAAIB3dsrwqXqD7E4zYYrxwdDKBUQxKMioXy9pxFVai64kAPxjU9KSqIo7QfkjslfsjflksjfldfkjsldfjLX/5zkzRmT28I5piGzunPv17S89z
++8XwSsuAoR1t86t+5dlI7eZE/gVbn2UQkQq7+kdDTS2yXV6VnC52N/kKLG3ciBkBAw== General Purpose RSA Key
++
++# search result
++search: 3
++result: 0 Success
++
++# numResponses: 2
++# numEntries: 1
++
++Now start a ssh session to user "testuser" from usual ssh client (e.g.
++puTTY). Login should succeed.
