Another exception (Sequence contains no matching element)

[RAB70]

Hi Seji,
thanks for the new build. but I got another error.
Depending on the settings:
"LAPS": {
"ForceVersion": "v2",
"EncryptionDisabled": true
},
I get different errors. When I set ForceVersion to null or "v2" I get the exception below. If I take v1 and set EncryptionDisabled to false, I get the message that I have no rights. The LAPS password is stored in the msLAPS-Password attribute. Do you have another idea?
Thanks

Please note that the LAPS ForceVersion enum changed and therefore null is not longer allowed.
Check the appsettings.json for the current values

Hi Seji,
I re-read and looked at your sources. In my case, the LAPS password is in plain text in the msLAPS-password attribute in the format
{"n":"LAPS admin","t":"1d9b97cb2bd3135","p":"LAPS password"}
All other laps attributes are empty. So I try the settings like this:
"LAPS": {
"ForceVersion": "v2", // Allowed Values: All, v1, v2 | Default: All (v1 & v2)
"EncryptionDisabled": true // Allowed Values: true, false | Default: false
},
In the source code I read that the attribute is also read in the TRY block for v2 (variable ldapValue ).
Unfortunately, I then get the error above.
In all other combinations of the LAPS settings, I get the message that I have no rights or that LAPS is not used, which is also logical, all other LAPS attributes are empty.
Do you have another tip?
Thanks
RAB

Seji, you are the GOAT! Thank you.
