The LDAP credential provider allows you to authenticate with LDAP.
|
|
To use it, first configure it through the "config" endpoint, and then
|
|
login by specifying username and password. If password is not provided
|
|
on the command line, it will be read from stdin.
|
|
|
|
If multi-factor authentication (MFA) is enabled, a "method" and/or "passcode"
|
|
may be provided depending on the MFA backend enabled. To check
|
|
which MFA backend is in use, read "auth/[mount]/mfa_config".
|
|
|
|
Example: vault auth -method=ldap username=john

|
|
