Usage: vault login -method=ldap [CONFIG K=V...]
|
|
|
|
The LDAP auth method allows users to authenticate using LDAP or
|
|
Active Directory.
|
|
|
|
If MFA is enabled, a "method" and/or "passcode" may be required depending on
|
|
the MFA method. To check which MFA is in use, run:
|
|
|
|
$ vault read auth/<mount>/mfa_config
|
|
|
|
Authenticate as "sally":
|
|
|
|
$ vault login -method=ldap username=sally
|
|
Password (will be hidden):
|
|
|
|
Authenticate as "bob":
|
|
|
|
$ vault login -method=ldap username=bob password=password
|
|
|
|
Configuration:
|
|
|
|
method=<string>
|
|
MFA method.
|
|
|
|
passcode=<string>
|
|
MFA OTP/passcode.
|
|
|
|
password=<string>
|
|
LDAP password to use for authentication. If not provided, the CLI will
|
|
prompt for this on stdin.
|
|
|
|
username=<string>
|
|
LDAP username to use for authentication.
