Describe the bug
On upgrading rancher server from 2.7.0 to 2.7-head, auth users are unable to login. This was seen on a fresh install of 2.7-head as well.

To Reproduce

1. Install rancher server on v2.7.0
2. Enable openldap/FreeIPA auth
3. Upgrade rancher server to v2.7-head
4. Try to login as an auth admin

Result
We get a 500 error whenever we try to login as an auth user:

baseType
: 
"error"
code
: 
"ServerError"
message
: 
"Server error while authenticating"
status
: 
500
type
: 
"error"

Following are the errors seen in docker logs when we try to login and for all the auth users that were added as cluster/project members:

2023/01/27 02:47:57 [ERROR] API error response 500 for POST /v3-public/freeIpaProviders/freeipa?action=login. Cause: invalid server config. at least 1 server needs to be configured
2023/01/27 02:48:03 [ERROR] API error response 500 for POST /v3-public/freeIpaProviders/freeipa?action=login. Cause: invalid server config. at least 1 server needs to be configured

2023/01/26 23:55:29 [ERROR] Unknown error: users.management.cattle.io "cn=<redacted>" not found
2023/01/26 23:55:29 [ERROR] Unknown error: users.management.cattle.io "cn=<redacted> not found
2023/01/26 23:55:29 [ERROR] Unknown error: users.management.cattle.io "cn=<redacted>" not found

If we login as a local admin and navigate back to the auth page, we see a few details that were previously configured were empty:

Expected Result
Expected the auth providers users to be able to login.

Additional context
This is not seen on 2.7.0, 2.6.10
This is not seen from 2.7.0 >> 2.7.1 but on an upgrade from 2.7.1 >> 2.7-head it is seen

Workaround:
Re add the config details for the auth that were missing.
