Delinea Secret Server - "Refresh token" option seems not working and it keeps prompting credentials after token expiration

Hi,

We are using currently 2026.1.14.0 64bit client under Windows 11.

We have implemented Delinea Secret Server solution with PAM distributed engines to be able to RDP connect onto our machines through PAM proxy, and it works great.

To be able to retrieve Delinea secrets info, we must first, for sure, provide Secret Server credentials when we launch the first related RDP session of the day and this part is working as expected.

At secret Server side, we've got this config :

Session Timeout for Webservices : 90 mins
Enable Refresh Tokens for Webservices : yes
Maximum Token Refreshes Allowed : 6

This should allow us not being asked for Secret Server credentials the whole day. But it seems not taking into account this "Enable Refresh Tokens for Webservices" option and prompts systematically to renter credentials for Secret Server login after 90 mins (then OK for the next 90 min and so on).

Could you check by your side or tell me what we miss, please ?

Thx
