++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.

++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

++
++# 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.
