# Extdom plugin protocol
SSSD on ipa client uses extdom plugin to translate SID to names and POSIX IDs. It can
also return secondary groups for any user.
## EXTDOM V0 (2.16.840.1.113730.3.8.10.4)
### V0 request
/*
* ExtdomRequestValue ::= SEQUENCE {
* inputType ENUMERATED {
* sid (1),
* name (2),
* posix uid (3),
* posix gid (4)
* },
* requestType ENUMERATED {
* simple (1),
* full (2)
* },
* data InputData
* }
*
* InputData ::= CHOICE {
* sid OCTET STRING,
* name NameDomainData
* uid PosixUid,
* gid PosixGid
* }
*
* NameDomainData ::= SEQUENCE {
* domain_name OCTET STRING,
* object_name OCTET STRING
* }
*
* PosixUid ::= SEQUENCE {
* domain_name OCTET STRING,
* uid INTEGER
* }
*
* PosixGid ::= SEQUENCE {
* domain_name OCTET STRING,
* gid INTEGER
* }
*/
### V0 reply
/*

*/
## EXTDOM V1 (2.16.840.1.113730.3.8.10.4.1)
In V1 version the requestType is extended of `full_with_groups`.
The response introduces new type `posix_user_grouplist` containing
the list of groups
### V1 request
/*
* ExtdomRequestValue ::= SEQUENCE {
* inputType ENUMERATED {

* name (2),
* posix uid (3),

### V1 reply

*

*
*/
## EXTDOM V2 (2.16.840.1.113730.3.8.10.4.2)
The `name` request tries to translate name to ID. It first tries translate it
as if it is a user and when it fails, it tries to resolve is as group.
To make it more efficient when SSSD knows the type of requested object, two new
inputTypes are defined - username and groupname.
The response is the same as in V1
### V2 request
/*
* ExtdomRequestValue ::= SEQUENCE {
* inputType ENUMERATED {
* sid (1),
* name (2),
* posix uid (3),
* posix gid (4),
* username (5),
* groupname (6)
* },
* requestType ENUMERATED {
* simple (1),
* full (2),
* full_with_groups (3)
* },
* data InputData
* }
*
* InputData ::= CHOICE {
* sid OCTET STRING,
* name NameDomainData
* uid PosixUid,
* gid PosixGid
* }
*
* NameDomainData ::= SEQUENCE {
* domain_name OCTET STRING,
* object_name OCTET STRING
* }

* PosixUid ::= SEQUENCE {
* domain_name OCTET STRING,
* uid INTEGER
