ElSigma wrote Hi, @Ethan-TP, thanks for your response. Yes, this LDAP server has been in production for around 3 years and I have multiple applications and Linux servers authenticating through it....

@GRL @Franklin7777 I did a test with my ER707-M2, it works with L2TP, firmware version on the router is 1.3.1 Build 20251009 Rel.67687
