4 cvtsudoers — convert between sudoers file formats
5
7 cvtsudoers [-ehMpV] [-b dn] [-c conf_file] [-d deftypes]
8 [-f output_format] [-i input_format] [-I increment]
9 [-m filter] [-o output_file] [-O start_point] [-s sections]
10 [input_file]
11
13 cvtsudoers can be used to convert between sudoers security policy file
14 formats. The default input format is sudoers. The default output format
15 is LDIF. It is only possible to convert a sudoers file that is syntacti‐
16 cally correct.
17
18 If no input_file is specified, or if it is ‘-’, the policy is read from
19 the standard input. By default, the result is written to the standard
20 output.
21
22 The options are as follows:
23
24 -b dn, --base=dn
25 The base DN (distinguished name) that will be used when per‐
26 forming LDAP queries. Typically this is of the form
27 ou=SUDOers,dc=-mydomain,dc=com for the domain my-domain.com.
28 If this option is not specified, the value of the
29 SUDOERS_BASE environment variable will be used instead. Only
30 necessary when converting to LDIF format.
31
32 -c, --config
33 Specify the path to a configuration file. Defaults to
34 /etc/cvtsudoers.conf.
35
36 -d deftypes, --defaults=deftypes
37 Only convert Defaults entries of the specified types. One or
38 more Defaults types may be specified, separated by a comma
39 (‘,’). The supported types are:
40
41 all All Defaults entries.
42
43 global Global Defaults entries that are applied regardless
44 of user, runas, host or command.
45
46 user Per-user Defaults entries.
47
48 runas Per-runas user Defaults entries.
49
50 host Per-host Defaults entries.
51
52 command Per-command Defaults entries.
53
54 See the Defaults section in sudoers(5) for more information.
55
56 If the -d option is not specified, all Defaults entries will
57 be converted.
58
59 -e, --expand-aliases
60 Expand aliases in input_file. Aliases are preserved by
61 default when the output format is JSON or sudoers.
62
63 -f output_format, --format=output_format
64 Specify the output format (case-insensitive). The following
65 formats are supported:
66
67 JSON JSON (JavaScript Object Notation) files are usually
68 easier for third-party applications to consume than
69 the traditional sudoers format. The various values
70 have explicit types which removes much of the ambi‐
71 guity of the sudoers format.
72
73 LDIF LDIF (LDAP Data Interchange Format) files can be
74 imported into an LDAP server for use with
75 sudoers.ldap(5).
76
77 Conversion to LDIF has the following limitations:
78
79 · Command, host, runas and user-specific Defaults
80 lines cannot be translated as they don't have an
81 equivalent in the sudoers LDAP schema.
82
83 · Command, host, runas and user aliases are not
84 supported by the sudoers LDAP schema so they are
85 expanded during the conversion.
86
87 sudoers Traditional sudoers format. A new sudoers file
88 will be reconstructed from the parsed input file.
89 Comments are not preserved and data from any
90 include files will be output inline.
91
92 -h, --help Display a short help message to the standard output and exit.
93
94 -i input_format, --input-format=input_format
95 Specify the input format. The following formats are sup‐
96 ported:
97
98 LDIF LDIF (LDAP Data Interchange Format) files can be
99 exported from an LDAP server to convert security
100 policies used by sudoers.ldap(5). If a base DN
101 (distinguished name) is specified, only sudoRole
102 objects that match the base DN will be processed.
103 Not all sudoOptions specified in a sudoRole can be
104 translated from LDIF to sudoers format.
105
106 sudoers Traditional sudoers format. This is the default
107 input format.
108
109 -I increment, --increment=increment
110 When generating LDIF output, increment each sudoOrder
111 attribute by the specified number. Defaults to an increment
112 of 1.
113
114 -m filter, --match=filter
115 Only output rules that match the specified filter. A filter
116 expression is made up of one or more key = value pairs, sepa‐
117 rated by a comma (‘,’). The key may be “user”, “group” or
118 “host”. For example, user = operator or host = www. An
119 upper-case User_Alias or Host_Alias may be specified as the
120 “user” or “host”.
121
122 A matching sudoers rule may also include users, groups and
123 hosts that are not part of the filter. This can happen when
124 a rule includes multiple users, groups or hosts. To prune
125 out any non-matching user, group or host from the rules, the
126 -p option may be used.
127
128 By default, the password and group databases are not con‐
129 sulted when matching against the filter so the users and
130 groups do not need to be present on the local system (see the
131 -M option). Only aliases that are referenced by the filtered
132 policy rules will be displayed.
133
134 -M, --match-local
135 When the -m option is also specified, use password and group
136 database information when matching users and groups in the
137 filter. Only users and groups in the filter that exist on
138 the local system will match, and a user's groups will auto‐
139 matically be added to the filter. If the -M is not speci‐
140 fied, users and groups in the filter do not need to exist on
141 the local system, but all groups used for matching must be
142 explicitly listed in the filter.
143
144 -o output_file, --output=output_file
145 Write the converted output to output_file. If no output_file
146 is specified, or if it is ‘-’, the converted sudoers policy
147 will be written to the standard output.
148
149 -O start_point, --order-start=start_point
150 When generating LDIF output, use the number specified by
151 start_point in the sudoOrder attribute of the first sudoRole
152 object. Subsequent sudoRole object use a sudoOrder value
153 generated by adding an increment, see the -I option for
154 details. Defaults to a starting point of 1. A starting
155 point of 0 will disable the generation of sudoOrder
156 attributes in the resulting LDIF file.
157
158 -p, --prune-matches
159 When the -m option is also specified, cvtsudoers will prune
160 out non-matching users, groups and hosts from matching
161 entries.
162
163 -s sections, --suppress=sections
164 Suppress the output of specific sections of the security pol‐
165 icy. One or more section names may be specified, separated
166 by a comma (‘,’). The supported section name are: defaults,
167 aliases and privileges (which may be shortened to privs).
168
169 -V, --version
170 Print the cvtsudoers and sudoers grammar versions and exit.
171
172 Options in the form “keyword = value” may also be specified in a configu‐
173 ration file, /etc/cvtsudoers.conf by default. The following keywords are
174 recognized:
175
176 defaults = deftypes
177 See the description of the -d command line option.
178
179 expand_aliases = yes | no
180 See the description of the -e command line option.
181
182 input_format = ldif | sudoers
183 See the description of the -i command line option.
184
185 match = filter
186 See the description of the -m command line option.
187
188 order_increment = increment
189 See the description of the -I command line option.
190
191 order_start = start_point
192 See the description of the -O command line option.
193
194 output_format = json | ldif | sudoers
195 See the description of the -f command line option.
196
197 prune_matches = yes | no
198 See the description of the -p command line option.
199
200 sudoers_base = dn
201 See the description of the -b command line option.
202
203 suppress = sections
204 See the description of the -s command line option.
205
206 Options on the command line will override values from the configuration
207 file.
208
210 /etc/cvtsudoers.conf default configuration for cvtsudoers
211
213 Convert /etc/sudoers to LDIF (LDAP Data Interchange Format) where the
214 ldap.conf file uses a sudoers_base of my-domain,dc=com, storing the
215 result in sudoers.ldif:
216
217 $ cvtsudoers -b ou=SUDOers,dc=my-domain,dc=com -o sudoers.ldif \
218 /etc/sudoers
219
220 Convert /etc/sudoers to JSON format, storing the result in sudoers.json:
221
222 $ cvtsudoers -f json -o sudoers.json /etc/sudoers
223
224 Parse /etc/sudoers and display only rules that match user ambrose on host
225 hastur:
226
227 $ cvtsudoers -f sudoers -m user=ambrose,host=hastur /etc/sudoers
228
229 Same as above, but expand aliases and prune out any non-matching users
230 and hosts from the expanded entries.
231
232 $ cvtsudoers -ep -f sudoers -m user=ambrose,host=hastur /etc/sudoers
233
234 Convert sudoers.ldif from LDIF to traditional sudoers format:
235
236 $ cvtsudoers -i ldif -f sudoers -o sudoers.new sudoers.ldif
