SAS URL \ No newline at end of file +There are a number of ways of supplying credentials for Azure Files +Storage. Rclone tries them in the order of the sections below. + +#### Env Auth + +If the `env_auth` config parameter is `true` then rclone will pull +credentials from the environment or runtime. + +It tries these authentication methods in this order: + +1. Environment Variables +2. Managed Service Identity Credentials +3. Azure CLI credentials (as used by the az tool) + +These are described in the following sections + +##### Env Auth: 1. Environment Variables + +If `env_auth` is set and environment variables are present rclone +authenticates a service principal with a secret or certificate, or a +user with a password, depending on which environment variable are set. +It reads configuration from these variables, in the following order: + +1. Service principal with client secret + - `AZURE_TENANT_ID`: ID of the service principal's tenant. Also called its "directory" ID. + - `AZURE_CLIENT_ID`: the service principal's client ID + - `AZURE_CLIENT_SECRET`: one of the service principal's client secrets +2. Service principal with certificate + - `AZURE_TENANT_ID`: ID of the service principal's tenant. Also called its "directory" ID. + - `AZURE_CLIENT_ID`: the service principal's client ID + - `AZURE_CLIENT_CERTIFICATE_PATH`: path to a PEM or PKCS12 certificate file including the private key. + - `AZURE_CLIENT_CERTIFICATE_PASSWORD`: (optional) password for the certificate file. + - `AZURE_CLIENT_SEND_CERTIFICATE_CHAIN`: (optional) Specifies whether an authentication request will include an x5c header to support subject name / issuer based authentication. When set to "true" or "1", authentication requests include the x5c header. +3. User with username and password + - `AZURE_TENANT_ID`: (optional) tenant to authenticate in. Defaults to "organizations". + - `AZURE_CLIENT_ID`: client ID of the application the user will authenticate to + - `AZURE_USERNAME`: a username (usually an email address) + - `AZURE_PASSWORD`: the user's password +4. Workload Identity + - `AZURE_TENANT_ID`: Tenant to authenticate in. + - `AZURE_CLIENT_ID`: Client ID of the application the user will authenticate to. + - `AZURE_FEDERATED_TOKEN_FILE`: Path to projected service account token file. + - `AZURE_AUTHORITY_HOST`: Authority of an Azure Active Directory endpoint (default: login.microsoftonline.com). + + +##### Env Auth: 2. Managed Service Identity Credentials + +When using Managed Service Identity if the VM(SS) on which this +program is running has a system-assigned identity, it will be used by +default. If the resource has no system-assigned but exactly one +user-assigned identity, the user-assigned identity will be used by +default. + +If the resource has multiple user-assigned identities you will need to +unset `env_auth` and set `use_msi` instead. See the [`use_msi` +section](#use_msi). + +##### Env Auth: 3. Azure CLI credentials (as used by the az tool) + +Credentials created with the `az` tool can be picked up using `env_auth`. + +For example if you were to login with a service principal like this: + + az login --service-principal -u XXX -p XXX --tenant XXX + +Then you could access rclone resources like this: + + rclone lsf :azurefiles,env_auth,account=ACCOUNT: + +Or + + rclone lsf --azurefiles-env-auth --azurefiles-account=ACCOUNT :azurefiles: + +#### Account and Shared Key + +This is the most straight forward and least flexible way. Just fill +in the `account` and `key` lines and leave the rest blank. + +#### SAS URL + +To use it leave `account`, `key` and `connection_string` blank and fill in `sas_url`. + +#### Connection String + +To use it leave `account`, `key` and "sas_url" blank and fill in `connection_string`. + +#### Service principal with client secret + +If these variables are set, rclone will authenticate with a service principal with a client secret. + +- `tenant`: ID of the service principal's tenant. Also called its "directory" ID. +- `client_id`: the service principal's client ID +- `client_secret`: one of the service principal's client secrets + +The credentials can also be placed in a file using the +`service_principal_file` configuration option. + +#### Service principal with certificate + +If these variables are set, rclone will authenticate with a service principal with certificate. + +- `tenant`: ID of the service principal's tenant. Also called its "directory" ID. +- `client_id`: the service principal's client ID +- `client_certificate_path`: path to a PEM or PKCS12 certificate file including the private key. +- `client_certificate_password`: (optional) password for the certificate file. +- `client_send_certificate_chain`: (optional) Specifies whether an authentication request will include an x5c header to support subject name / issuer based authentication. When set to "true" or "1", authentication requests include the x5c header. + +**NB** `client_certificate_password` must be obscured - see [rclone obscure](/commands/rclone_obscure/). + +#### User with username and password + +If these variables are set, rclone will authenticate with username and password. + +- `tenant`: (optional) tenant to authenticate in. Defaults to "organizations". +- `client_id`: client ID of the application the user will authenticate to +- `username`: a username (usually an email address) +- `password`: the user's password + +Microsoft doesn't recommend this kind of authentication, because it's +less secure than other authentication flows. This method is not +interactive, so it isn't compatible with any form of multi-factor +authentication, and the application must already have user or admin +consent. This credential can only authenticate work and school +accounts; it can't authenticate Microsoft accounts. + +**NB** `password` must be obscured - see [rclone obscure](/commands/rclone_obscure/). + +#### Managed Service Identity Credentials {#use_msi} + +If `use_msi` is set then managed service identity credentials are +used.
