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 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 The options are as follows:
23 -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 -c conf_file, --config=conf_file
33 Specify the path to the configuration file. Defaults to
34 /etc/cvtsudoers.conf.
35 -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 all All Defaults entries.
42 global Global Defaults entries that are applied regardless
44 of user, runas, host or command.
45 user Per-user Defaults entries.
47 runas Per-runas user Defaults entries.
49 host Per-host Defaults entries.
51 command Per-command Defaults entries.
53 See the Defaults section in sudoers(5) for more information.
55 If the -d option is not specified, all Defaults entries will
57 be converted.
58 -e, --expand-aliases
60 Expand aliases in input_file. Aliases are preserved by
61 default when the output format is JSON or sudoers.
62 -f output_format, --output-format=output_format
64 Specify the output format (case-insensitive). The following
65 formats are supported:
66 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 LDIF LDIF (LDAP Data Interchange Format) files can be
74 imported into an LDAP server for use with
75 sudoers.ldap(5).
76 Conversion to LDIF has the following limitations:
78 · 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 · Command, host, runas and user aliases are not
84 supported by the sudoers LDAP schema so they are
85 expanded during the conversion.
86 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 -h, --help Display a short help message to the standard output and exit.
93 -i input_format, --input-format=input_format
95 Specify the input format. The following formats are sup‐
96 ported:
97 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 sudoers Traditional sudoers format. This is the default
107 input format.
108 -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 -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 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 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 -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 -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 -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 -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 -P padding, --padding=padding
164 When generating LDIF output, construct the initial sudoOrder
165 value by concatenating order_start and increment, padding the
166 increment with zeros until it consists of padding digits.
167 For example, if order_start is 1027, padding is 3, and
168 increment is 1, the value of sudoOrder for the first entry
169 will be 1027000, followed by 1027001, 1027002, etc. If the
170 number of sudoRole entries is larger than the padding would
171 allow, cvtsudoers will exit with an error. By default, no
172 padding is performed.
173 -s sections, --suppress=sections
175 Suppress the output of specific sections of the security pol‐
176 icy. One or more section names may be specified, separated
177 by a comma (‘,’). The supported section name are: defaults,
178 aliases and privileges (which may be shortened to privs).
179 -V, --version
181 Print the cvtsudoers and sudoers grammar versions and exit.
182 Options in the form “keyword = value” may also be specified in a configu‐
184 ration file, /etc/cvtsudoers.conf by default. The following keywords are
185 recognized:
186 defaults = deftypes
188 See the description of the -d command line option.
189 expand_aliases = yes | no
191 See the description of the -e command line option.
192 input_format = ldif | sudoers
194 See the description of the -i command line option.
195 match = filter
197 See the description of the -m command line option.
198 order_increment = increment
200 See the description of the -I command line option.
201 order_start = start_point
203 See the description of the -O command line option.
204 output_format = json | ldif | sudoers
206 See the description of the -f command line option.
207 padding = padding
209 See the description of the -P command line option.
210 prune_matches = yes | no
212 See the description of the -p command line option.
213 sudoers_base = dn
215 See the description of the -b command line option.
216 suppress = sections
218 See the description of the -s command line option.
219 Options on the command line will override values from the configuration
221 file.
222
224 /etc/cvtsudoers.conf default configuration for cvtsudoers
225
227 Convert /etc/sudoers to LDIF (LDAP Data Interchange Format) where the
228 ldap.conf file uses a sudoers_base of my-domain,dc=com, storing the
229 result in sudoers.ldif:
230 $ cvtsudoers -b ou=SUDOers,dc=my-domain,dc=com -o sudoers.ldif \
232 /etc/sudoers
233 Convert /etc/sudoers to JSON format, storing the result in sudoers.json:
235 $ cvtsudoers -f json -o sudoers.json /etc/sudoers
237 Parse /etc/sudoers and display only rules that match user ambrose on host
239 hastur:
240 $ cvtsudoers -f sudoers -m user=ambrose,host=hastur /etc/sudoers
242 Same as above, but expand aliases and prune out any non-matching users
244 and hosts from the expanded entries.
245 $ cvtsudoers -ep -f sudoers -m user=ambrose,host=hastur /etc/sudoers
247 Convert sudoers.ldif from LDIF to traditional sudoers format:
249 $ cvtsudoers -i ldif -f sudoers -o sudoers.new sudoers.ldif
