1.1.1.3 misho 26: In addition to the standard
27: \fIsudoers\fR
28: file,
29: \fBsudo\fR
30: may be configured
31: via LDAP.
32: This can be especially useful for synchronizing
33: \fIsudoers\fR
1.1 misho 34: in a large, distributed environment.
35: .PP
1.1.1.3 misho 36: Using LDAP for
37: \fIsudoers\fR
38: has several benefits:
39: .TP 4n
40: \fBo\fR
41: \fBsudo\fR
42: no longer needs to read
43: \fIsudoers\fR
44: in its entirety.
45: When LDAP is used, there are only two or three LDAP queries per invocation.
46: This makes it especially fast and particularly usable in LDAP environments.
47: .TP 4n
48: \fBo\fR
49: \fBsudo\fR
50: no longer exits if there is a typo in
51: \fIsudoers\fR.
52: It is not possible to load LDAP data into the server that does
1.1 misho 53: not conform to the sudoers schema, so proper syntax is guaranteed.
54: It is still possible to have typos in a user or host name, but
1.1.1.3 misho 55: this will not prevent
56: \fBsudo\fR
57: from running.
58: .TP 4n
59: \fBo\fR
1.1 misho 60: It is possible to specify per-entry options that override the global
1.1.1.3 misho 61: default options.
62: \fI@sysconfdir@/sudoers\fR
63: only supports default options and limited options associated with
64: user/host/commands/aliases.
65: The syntax is complicated and can be difficult for users to understand.
1.1 misho 66: Placing the options directly in the entry is more natural.
1.1.1.3 misho 67: .TP 4n
68: \fBo\fR
69: The
70: \fBvisudo\fR
71: program is no longer needed.
72: \fBvisudo\fR
73: provides locking and syntax checking of the
74: \fI@sysconfdir@/sudoers\fR
75: file.
76: Since LDAP updates are atomic, locking is no longer necessary.
77: Because syntax is checked when the data is inserted into LDAP, there
1.1 misho 78: is no need for a specialized tool to check syntax.
79: .PP
1.1.1.3 misho 80: Another major difference between LDAP and file-based
81: \fIsudoers\fR
82: is that in LDAP,
83: \fBsudo\fR-specific
84: Aliases are not supported.
85: .PP
86: For the most part, there is really no need for
87: \fBsudo\fR-specific
88: Aliases.
1.1.1.4 misho 89: Unix groups, non-Unix groups (via the
90: \fIgroup_plugin\fR)
91: or user netgroups can be used in place of User_Aliases and Runas_Aliases.
1.1.1.3 misho 92: Host netgroups can be used in place of Host_Aliases.
1.1.1.4 misho 93: Since groups and netgroups can also be stored in LDAP there is no real need for
1.1.1.3 misho 94: \fBsudo\fR-specific
95: aliases.
1.1 misho 96: .PP
97: Cmnd_Aliases are not really required either since it is possible
1.1.1.3 misho 98: to have multiple users listed in a
99: \fRsudoRole\fR.
100: Instead of defining a Cmnd_Alias that is referenced by multiple users,
101: one can create a
102: \fRsudoRole\fR
103: that contains the commands and assign multiple users to it.
104: .SS "SUDOers LDAP container"
105: The
106: \fIsudoers\fR
107: configuration is contained in the
108: \fRou=SUDOers\fR
109: LDAP container.
110: .PP
111: Sudo first looks for the
112: \fRcn=default\fR
113: entry in the SUDOers container.
114: If found, the multi-valued
115: \fRsudoOption\fR
116: attribute is parsed in the same manner as a global
117: \fRDefaults\fR
118: line in
119: \fI@sysconfdir@/sudoers\fR.
120: In the following example, the
121: \fRSSH_AUTH_SOCK\fR
122: variable will be preserved in the environment for all users.

157: \fRsudoRole\fR

1.1.1.3 misho 159: .TP 6n

174: The built-in command
1.1.1.6 ! misho 175: \(lq\fRsudoedit\fR\(rq

183: Note that
1.1.1.6 ! misho 184: \(lq\fRsudoedit\fR\(rq
1.1.1.4 misho 185: is a command built into

188: .sp
1.1.1.3 misho 189: The special value
190: \fRALL\fR

1.1.1.4 misho 192: .sp
193: If a command name is prefixed with a SHA-2 digest, it will
194: only be allowed if the digest matches.
195: This may be useful in situations where the user invoking
196: \fBsudo\fR
197: has write access to the command or its parent directory.

360: .SS "Anatomy of LDAP sudoers lookup"
361: When looking up a sudoer using LDAP there are only two or three
362: LDAP queries per invocation.
363: The first query is to parse the global options.
364: The second is to match against the user's name and the groups that
365: the user belongs to.
366: (The special
367: \fRALL\fR
368: tag is matched in this query too.)
369: If no match is returned for the user's name and groups, a third

373: If timed entries are enabled with the

1.1 misho 378: There are some subtle differences in the way sudoers is handled
1.1.1.3 misho 379: once in LDAP.

388: within a specific entry.

758: If

761: Note that disabling the check creates an opportunity for man-in-the-middle
