6 autofs_ldap_auth.conf - autofs LDAP authentication configuration
7
9 LDAP authenticated binds, TLS encrypted connections and certification
10 may be used by setting appropriate values in the autofs authentication
11 configuration file and configuring the LDAP client with appropriate
12 settings. The default location of this file is
13 /etc/autofs_ldap_auth.conf. If this file exists it will be used to es‐
14 tablish whether TLS or authentication should be used.
15 An example of this file is:
17 <?xml version="1.0" ?>
19 <autofs_ldap_sasl_conf
20 usetls="yes"
21 tlsrequired="no"
22 authrequired="no"
23 authtype="DIGEST-MD5"
24 user="xyz"
25 secret="abc"
26 />
27 If TLS encryption is to be used the location of the Certificate Author‐
29 ity certificate must be set within the LDAP client configuration in or‐
30 der to validate the server certificate. If, in addition, a certified
31 connection is to be used then the client certificate and private key
32 file locations must also be configured within the LDAP client.
33
35 This files contains a single XML element, as shown in the example
36 above, with several attributes.
37 The possible attributes are:
39 usetls="yes"|"no"
41 Determines whether an encrypted connection to the ldap server
42 should be attempted.
43 tlsrequired="yes"|"no"
45 This flag tells whether the ldap connection must be encrypted.
46 If set to "yes", the automounter will fail to start if an en‐
47 crypted connection cannot be established.
48 authrequired="yes"|"no"|"autodetect"|"simple"
50 This option tells whether an authenticated connection to the
51 ldap server is required in order to perform ldap queries. If the
52 flag is set to yes, only sasl authenticated connections will be
53 allowed. If it is set to no then authentication is not needed
54 for ldap server connections. If it is set to autodetect then the
55 ldap server will be queried to establish a suitable sasl authen‐
56 tication mechanism. If no suitable mechanism can be found, con‐
57 nections to the ldap server are made without authentication. Fi‐
58 nally, if it is set to simple, then simple authentication will
59 be used instead of SASL.
60 authtype="GSSAPI"|"LOGIN"|"PLAIN"|"ANONYMOUS"|"DIGEST-MD5|EXTERNAL"
62 This attribute can be used to specify a preferred authentication
63 mechanism. In normal operations, the automounter will attempt
64 to authenticate to the ldap server using the list of supported‐
65 SASLmechanisms obtained from the directory server. Explicitly
66 setting the authtype will bypass this selection and only try the
67 mechanism specified. The EXTERNAL mechanism may be used to au‐
68 thenticate using a client certificate and requires that authre‐
69 quired set to "yes" if using SSL or usetls, tlsrequired and au‐
70 threquired all set to "yes" if using TLS, in addition to au‐
71 thtype being set to EXTERNAL.
72 If using authtype EXTERNAL two additional configuration entries
74 are required:
75 external_cert="<client certificate path>"
77 This specifies the path of the file containing the client cer‐
79 tificate.
80 external_key="<client certificate key path>"
82 This specifies the path of the file containing the client cer‐
84 tificate key.
85 These two configuration entries are mandatory when using the EX‐
87 TERNAL method as the HOME environment variable cannot be assumed
88 to be set or, if it is, to be set to the location we expect.
89 user="<username>"
91 This attribute holds the authentication identity used by authen‐
92 tication mechanisms that require it. Legal values for this at‐
93 tribute include any printable characters that can be used by the
94 selected authentication mechanism.
95 secret="<password>"
97 This attribute holds the secret used by authentication mecha‐
98 nisms that require it. Legal values for this attribute include
99 any printable characters that can be used by the selected au‐
100 thentication mechanism.
101 encoded_secret="<base64 encoded password>"
103 This attribute holds the base64 encoded secret used by authenti‐
104 cation mechanisms that require it. If this entry is present as
105 well as the secret entry this value will take precedence.
106 clientprinc="<GSSAPI client principal>"
109 When using GSSAPI authentication, this attribute is con‐
110 sulted to determine the principal name to use when au‐
111 thenticating to the directory server. By default, this
112 will be set to "autofsclient/<fqdn>@<REALM>.
113 credentialcache="<external credential cache path>"
115 When using GSSAPI authentication, this attribute can be
116 used to specify an externally configured credential cache
117 that is used during authentication. By default, autofs
118 will setup a memory based credential cache.
