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] [-P padding]
10 [-s sections] [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=my-domain,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 conf_file, --config=conf_file
33 Specify the path to the 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 de‐
61 fault when the output format is JSON or sudoers.
62
63 -f output_format, --output-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 in‐
90 clude 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 attri‐
111 bute by the specified number. Defaults to an increment of 1.
112
113 -m filter, --match=filter
114 Only output rules that match the specified filter. A filter
115 expression is made up of one or more key = value pairs, sepa‐
116 rated by a comma (‘,’). The key may be “user”, “group” or
117 “host”. For example, user = operator or host = www. An up‐
118 per-case User_Alias or Host_Alias may be specified as the
119 “user” or “host”.
120
121 A matching sudoers rule may also include users, groups and
122 hosts that are not part of the filter. This can happen when
123 a rule includes multiple users, groups or hosts. To prune
124 out any non-matching user, group or host from the rules, the
125 -p option may be used.
126
127 By default, the password and group databases are not con‐
128 sulted when matching against the filter so the users and
129 groups do not need to be present on the local system (see the
130 -M option). Only aliases that are referenced by the filtered
131 policy rules will be displayed.
132
133 -M, --match-local
134 When the -m option is also specified, use password and group
135 database information when matching users and groups in the
136 filter. Only users and groups in the filter that exist on
137 the local system will match, and a user's groups will auto‐
138 matically be added to the filter. If the -M is not speci‐
139 fied, users and groups in the filter do not need to exist on
140 the local system, but all groups used for matching must be
141 explicitly listed in the filter.
142
143 -o output_file, --output=output_file
144 Write the converted output to output_file. If no output_file
145 is specified, or if it is ‘-’, the converted sudoers policy
146 will be written to the standard output.
147
148 -O start_point, --order-start=start_point
149 When generating LDIF output, use the number specified by
150 start_point in the sudoOrder attribute of the first sudoRole
151 object. Subsequent sudoRole object use a sudoOrder value
152 generated by adding an increment, see the -I option for de‐
153 tails. Defaults to a starting point of 1. A starting point
154 of 0 will disable the generation of sudoOrder attributes in
155 the resulting LDIF file.
156
157 -p, --prune-matches
158 When the -m option is also specified, cvtsudoers will prune
159 out non-matching users, groups and hosts from matching en‐
160 tries.
161
162 -P padding, --padding=padding
163 When generating LDIF output, construct the initial sudoOrder
164 value by concatenating order_start and increment, padding the
165 increment with zeros until it consists of padding digits.
166 For example, if order_start is 1027, padding is 3, and
167 increment is 1, the value of sudoOrder for the first entry
168 will be 1027000, followed by 1027001, 1027002, etc. If the
169 number of sudoRole entries is larger than the padding would
170 allow, cvtsudoers will exit with an error. By default, no
171 padding is performed.
172
173 -s sections, --suppress=sections
174 Suppress the output of specific sections of the security pol‐
175 icy. One or more section names may be specified, separated
176 by a comma (‘,’). The supported section name are: defaults,
177 aliases and privileges (which may be shortened to privs).
178
179 -V, --version
180 Print the cvtsudoers and sudoers grammar versions and exit.
181
182 Options in the form “keyword = value” may also be specified in a configu‐
183 ration file, /etc/cvtsudoers.conf by default. The following keywords are
184 recognized:
185
186 defaults = deftypes
187 See the description of the -d command line option.
188
189 expand_aliases = yes | no
190 See the description of the -e command line option.
191
192 input_format = ldif | sudoers
193 See the description of the -i command line option.
194
195 match = filter
196 See the description of the -m command line option.
197
198 order_increment = increment
199 See the description of the -I command line option.
200
201 order_start = start_point
202 See the description of the -O command line option.
203
204 output_format = json | ldif | sudoers
205 See the description of the -f command line option.
206
207 padding = padding
208 See the description of the -P command line option.
209
210 prune_matches = yes | no
211 See the description of the -p command line option.
212
213 sudoers_base = dn
214 See the description of the -b command line option.
215
216 suppress = sections
217 See the description of the -s command line option.
218
219 Options on the command line will override values from the configuration
220 file.
221
223 /etc/cvtsudoers.conf default configuration for cvtsudoers
224
226 Convert /etc/sudoers to LDIF (LDAP Data Interchange Format) where the
227 ldap.conf file uses a sudoers_base of my-domain,dc=com, storing the re‐
228 sult in sudoers.ldif:
229
230 $ cvtsudoers -b ou=SUDOers,dc=my-domain,dc=com -o sudoers.ldif \
231 /etc/sudoers
232
233 Convert /etc/sudoers to JSON format, storing the result in sudoers.json:
234
235 $ cvtsudoers -f json -o sudoers.json /etc/sudoers
236
237 Parse /etc/sudoers and display only rules that match user ambrose on host
238 hastur:
239
240 $ cvtsudoers -f sudoers -m user=ambrose,host=hastur /etc/sudoers
241
242 Same as above, but expand aliases and prune out any non-matching users
243 and hosts from the expanded entries.
244
245 $ cvtsudoers -ep -f sudoers -m user=ambrose,host=hastur /etc/sudoers
246
247 Convert sudoers.ldif from LDIF to traditional sudoers format:
248
249 $ cvtsudoers -i ldif -f sudoers -o sudoers.new sudoers.ldif
