# HG changeset patch
# Parent  b8135c449e59282a8926ff44fcb4670baf8f158e
# Helper app for retrieving keys from a LDAP server
# by Jan F. Chadima <jchadima@redhat.com>
#
# patch for openbsd-compat/base64.* introduces preprocessor macro
# USE_INTERNAL_B64 intended to enforce using ssh supplied functions.
# (The additional -lldap/-llber introduced in the patch cause configure to
# discover the base64 functions in glibc (libresolv) and not to build the
# internal versions. ssh-keyconverter consequently fails to link as it lacks
# the proper flags, and libopenbsd-compat doesn't contain the b64_* functions)

+
+HOW TO START
+
+1) configure LDAP server
+  * Use LDAP server documentation
+2) add appropriate LDAP schema
+  * For OpenLDAP or SunONE Use attached schema, otherwise you have to create
+    it. 
+  * LDAP user entry
+        User entry:
+	- attached to the 'ldapPublicKey' objectclass
+	- attached to the 'posixAccount' objectclass
+	- with a filled 'sshPublicKey' attribute 
+3) insert users into LDAP
+  * Use LDAP Tree management tool as useful
+  * Entry in the LDAP server must respect 'posixAccount' and 'ldapPublicKey'
+    which are defined in core.schema and the additionnal lpk.schema.
+  * Example:
+	dn: uid=captain,ou=commanders,dc=enterprise,dc=universe
+	objectclass: top
+	objectclass: person
+	objectclass: organizationalPerson
+	objectclass: posixAccount
+	objectclass: ldapPublicKey
+	description: Jonathan Archer
+	userPassword: Porthos
+	cn: onathan Archer
+	sn: onathan Archer
+	uid: captain
+	uidNumber: 1001
+	gidNumber: 1001
+	homeDirectory: /home/captain
+	sshPublicKey: ssh-rss AAAAB3.... =captain@universe
+	sshPublicKey: command="kill -9 1" ssh-rss AAAAM5...
+4) on the ssh side set in sshd_config
+  * Set up the backend
+	AuthorizedKeysCommand "@LIBEXECDIR@/ssh-ldap-wrapper"
+	AuthorizedKeysCommandRunAs <appropriate user to run LDAP>
+  * Do not forget to set
+	PubkeyAuthentication yes
+  * Swith off unnecessary auth methods
+5) confugure ldap.conf
+  * Default ldap.conf is placed in /etc/ssh
+  * The configuration style is the same as other ldap based aplications
+6) if necessary edit ssh-ldap-wrapper
+  * There is a possibility to change ldap.conf location
+  * There are some debug options
+  * Example
+	@LIBEXECDIR@/ssh-ldap-wrapper -s -f /etc/ldap.conf -w -d >> /tmp/ldapdebuglog.txt
+
+HOW TO MIGRATE FROM LPK
+
+1) goto HOW TO START 4) .... the ldap schema is the same
+
+2) convert the group requests to the appropriate LDAP requests
+
+HOW TO SOLVE PROBLEMS
+
+1) use debug in sshd
+  * /usr/sbin/sshd -d -d -d -d
+2) use debug in ssh-ldap-helper
+  * ssh-ldap-helper -d -d -d -d -s <username>
+3) use tcpdump ... other ldap client etc.
+
+ADVANTAGES
+
+1) Blocking an user account can be done directly from LDAP (if sshd is using
+   PubkeyAuthentication + AuthorizedKeysCommand with ldap only).
+
+DISADVANTAGES
+
+1) LDAP must be well configured, getting the public key of some user is not
+   a problem, but if anonymous LDAP allows write to users dn, somebody could
+   replace some user's public key by his own and impersonate some of your users
+   in all your server farm -- be VERY CAREFUL.
+2) With incomplete PKI the MITM attack when sshd is requesting the public key,
+   could lead to a compromise of your servers allowing login as the
+   impersonated user.
+3) If LDAP server is down there may be no fallback on passwd auth.
+  
+MISC.
+  
+1) todo
+  * Possibility to reuse the ssh-ldap-helper.
+  * Tune the LDAP part to accept  all possible LDAP configurations.
+
+2) differences from original lpk
+  * No LDAP code in sshd.
+  * Support for various LDAP platforms and configurations.
+  * LDAP is configured in separate ldap.conf file.
+
+3) docs/link 
+  * http://pacsec.jp/core05/psj05-barisani-en.pdf

+.Sh NAME
+.Nm ssh-ldap.conf
+.Nd configuration file for ssh-ldap-helper
+.Sh SYNOPSIS
+.Nm /etc/ssh/ldap.conf
+.Sh DESCRIPTION
+.Xr ssh-ldap-helper 8
+reads configuration data from
+.Pa /etc/ssh/ldap.conf
+(or the file specified with
+.Fl f
+on the command line).
+The file contains keyword-argument pairs, one per line.
+Lines starting with
+.Ql #
+and empty lines are interpreted as comments.
+.Pp
+The value starts with the first non-blank character after 
+the keyword's name, and terminates at the end of the line, 
+or at the last sequence of blanks before the end of the line.
+Quoting values that contain blanks 
+may be incorrect, as the quotes would become part of the value.
+The possible keywords and their meanings are as follows (note that
+keywords are case-insensitive, and arguments, on a case by case basis, may be case-sensitive).
+.Bl -tag -width Ds
+.It Cm URI
+The argument(s) are in the form
+.Pa ldap[si]://[name[:port]]
+and specify the URI(s) of an LDAP server(s) to which the
+.Xr ssh-ldap-helper 8 
+should connect. The URI scheme may be any of
+.Dq ldap ,
+.Dq ldaps 
+or
+.Dq ldapi ,
+which refer to LDAP over TCP, LDAP over SSL (TLS) and LDAP
+over IPC (UNIX domain sockets), respectively.
+Each server's name can be specified as a
+domain-style name or an IP address literal.  Optionally, the
+server's name can followed by a ':' and the port number the LDAP
+server is listening on.  If no port number is provided, the default
+port for the scheme is used (389 for ldap://, 636 for ldaps://).
+For LDAP over IPC, name is the name of the socket, and no port
+is required, nor allowed; note that directory separators must be 
+URL-encoded, like any other characters that are special to URLs; 
+A space separated list of URIs may be provided.
+There is no default.
+.It Cm Base
+Specifies the default base Distinguished Name (DN) to use when performing ldap operations.
+The base must be specified as a DN in LDAP format.
+There is no default.
+.It Cm BindDN
+Specifies the default BIND DN to use when connecting to the ldap server.
+The bind DN must be specified as a Distinguished Name in LDAP format.
+There is no default.
+.It Cm BindPW
+Specifies the default password to use when connecting to the ldap server via
+.Cm BindDN .
+There is no default.
+.It Cm RootBindDN
+Intentionaly does nothing. Recognized for compatibility reasons.
+.It Cm Host
+The argument(s) specifies the name(s) of an LDAP server(s) to which the
+.Xr ssh-ldap-helper 8
+should connect.  Each server's name can be specified as a
+domain-style name or an IP address and optionally followed by a ':' and
+the port number the ldap server is listening on.  A space-separated
+list of hosts may be provided.
+There is no default.
+.Cm Host
+is deprecated in favor of
+.Cm URI .
+.It Cm Port
+Specifies the default port used when connecting to LDAP servers(s).
+The port may be specified as a number.
+The default port is 389 for ldap:// or 636 for ldaps:// respectively.
+.Cm Port
+is deprecated in favor of
+.Cm URI .
+.It Cm Scope
+Specifies the starting point of an LDAP search and the depth from the base DN to which the search should descend.
+There are three options (values) that can be assigned to the
+.Cm Scope parameter:
+.Dq base ,
+.Dq one
+and
+.Dq subtree .
+Alias for the subtree is
+.Dq sub .
+The value
+.Dq base
+is used to indicate searching only the entry at the base DN, resulting in only that entry being returned (keeping in mind that it also has to meet the search filter criteria!).
+The value
+.Dq one
+is used to indicate searching all entries one level under the base DN, but not including the base DN and not including any entries under that one level under the base DN.
+The value
+.Dq subtree
+is used to indicate searching of all entries at all levels under and including the specified base DN.
+The default is
+.Dq subtree .
+.It Cm Deref
+Specifies how alias dereferencing is done when performing a search. There are four
+possible values that can be assigned to the
+.Cm Deref
+parameter:

+.Dq always .
+The value
+.Dq never
+means that the aliases are never dereferenced.
+The value
+.Dq searching
+means that the aliases are dereferenced in subordinates of the base object, but
+not in locating the base object of the search.

+means that the aliases are only dereferenced when locating the base object of the search.
+The value
+.Dq always
+means that the aliases are dereferenced both in searching and in locating the base object
+of the search.
+The default is
+.Dq never .
+.It Cm TimeLimit
+Specifies a time limit (in seconds) to use when performing searches.
+The number should be a non-negative integer. A
+.Cm TimeLimit

+.Dq hard has 2 aliases
+.Dq hard_open
+and
+.Dq hard_init .
+The value
+.Dq hard
+means that reconects that the
+.Xr ssh-ldap-helper 8
+tries to reconnect to the LDAP server 5 times before failure. There is exponential backoff before retrying.
+The value
+.Dq soft
+means that
+.Xr ssh-ldap-helper 8
+fails immediately when it cannot connect to the LDAP seerver.
+The deault is
+.Dq hard .
