[for 10.4] Receive multiple users from backend for user sync

[sharidas]

Receive multiple users from the backend for user sync
instead of checking for single user. From the received
users check if the user to be synced is available in
the list.

Signed-off-by: Sujith H sharidasan@owncloud.com

Description

Problem: When admin tries to sync a user say for ldap backend, there can be cases where names like mhof, mhoff, mhoffg exist in the ldap. And when admin tries to sync mhof, the admin gets Multiple user exists exception.

What this PR proposes:
Grab all the users available from the user backend, which the admin had searched for. And then try to match the users with the user to be searched for. If there are multiple users with same user name available then throw the exception. If only one user is available then sync it, else as usual show message saying user does not exist in the backend.

Related Issue

• Fixes enterprise ticket 3447

Motivation and Context

Do not check for the count of users. Instead check if the users received from the backend contains the exact match or not.

How Has This Been Tested?

• Created LDAP setup
• Created LDAP users mhof, mhoff, mhoffg
• Now as oC admin tried to sync the user mhof

sujith@sujith-ownCloud  ~/test/owncloud   fix-sync-user ●  ./occ user:sync "OCA\User_LDAP\User_Proxy" -u 'mhof'          
Cannot load Xdebug - it was already loaded
If unknown users are found, what do you want to do with their accounts? (removing the account will also remove its data)
  [0] disable
  [1] remove
  [2] ask later
 > 0
Syncing mhof ...

 sujith@sujith-ownCloud  ~/test/owncloud   fix-sync-user ● 

• As admin user try to sync mhoffg123 which does not exist:

sujith@sujith-ownCloud  ~/test/owncloud   fix-sync-user ●  ./occ user:sync "OCA\User_LDAP\User_Proxy" -u 'mhoffg123'
Cannot load Xdebug - it was already loaded

  [0] disable

Disabling accounts:

Code looks good.

[phil-davis]

I added issue #36597 to make CLI acceptance tests.
We do not seem to have any acceptance tests for the user:sync command - so we won't hold up merging this PR.

@sharidas

1. Is there an issue to link to in the top post?
2. needs a changelog item

[sharidas]

@phil-davis
