Tested this with slapd and it worked nicely! I found two small issues,
see below.
Tested-by: Friedrich Weber <f.weber at proxmox.com>
## Sync fails if some LDAP user attribute violates API schema
1) Create LDAP users:
* "a" with givenName "a" (one character)
* "foo" with givenName "foo"
2) Add an LDAP realm, set "First Name attribute" to "givenName"
3) Sync->Preview succeeds
4) Sync->Sync fails with:
2023-02-10T14:44:14+01:00: starting realm sync for ldap
2023-02-10T14:44:14+01:00: creating user a at ldap
2023-02-10T14:44:14+01:00: creating user foo at ldap
2023-02-10T14:44:14+01:00: TASK ERROR: could not store user config
No new users were created. Not creating "a" is okay, as the API schema
requires firstnames to have length >=2, but the sync should probably
just skip "a" with a warning and create "foo" anyway.
## Web UI shows an error after editing an LDAP realm
1) Add an LDAP realm with default settings
2) Edit the realm and set "user classes" to "inetorgperson", click OK
3) Error message dialog "parameter verification errors" / "delete: value
'filter,sync-defaults-options,sync-attributes' is not defined in the
enumeration"
The decoded form data of the corresponding PUT request sets:
"delete": [
"server2",
"port",
"bind-dn",
"password",
"filter,sync-defaults-options,sync-attributes"
]
... which looks like some parsing logic got confused somewhere and fused
the last three items together.
