| Session | Required: the session ID from LogIn in the mfiles-session-id-bin metadata. |
| Idempotent | no |
| Returns metadata structure version | no |

login_data.vault_guid | string | The vault to log in to, as a GUID string with or without braces, in any case. Use {00000000-0000-0000-0000-000000000000} for a server-level session; an empty string is rejected with E_MFILES_INVALID_VAULT_GUID_X_DESC. |
login_data.is_administrative | bool | True for administrative tools that manage the vault rather than work with documents, as M-Files Admin does. Applications leave it false. |
login_data.client_session_timeout_in_seconds | uint32 | Optional. Requests a longer idle timeout for a vault session. Honored only when it is at least the server's session timeout and at most 7 days (or the server timeout if that is longer); otherwise, and for server-level sessions, the server timeout applies. The effective value shows as SessionData.keep_alive_interval_in_seconds, which is half of it. |

| Field | Type | Description |
|---|---|---|
session_data | SessionData | The session. Use its session_id from now on. |
session_data.session_id | bytes | The session ID (48 bytes). Send it unchanged in the mfiles-session-id-bin metadata header of every call that needs a session. |
session_data.account_name | string | The login account name, with the case stored on the server. |
session_data.access_rights | SessionAccess | What the session may do on server level and in the vault, regardless of object permissions. |
session_data.server_vault_capabilities | ServerVaultCapabilities | Capabilities of the server and, for vault sessions, the vault, as they apply to this user. More precise than GetServerCapabilities. |
session_data.locale | uint32 | The Windows locale ID used for sorting, for example 1033. |
session_data.keep_alive_interval_in_seconds | uint32 | Call KeepAlive at least this often. It is half of the session's idle timeout. |
session_data.use_strict_set_equality_comparison | bool | If false, not equal type comparisons are performed in pre-MF11 style in which it is enough that at least one of the left-side values does not match any of the right-side values in order to treat the left and right values unequal. If true, none of the left-side values can match any of the right-side values in order to treat the left and right values unequal i.e. pure set-based exclusion. Prefer using the new comparison style. The old behavior is provided for compatibility reasons. |
