Microsoft announced a change in Conditional Access via Message Center - I'm talking about Entra's Baseline scope settings enforcement. OIDC Apps like Citrix DaaS or NetScaler might be affected. Checkout: www.julianjakob.com/microsoft-en...

At the moment, public CA SSL/TLS-Certificates use a maximum Lifetime of 199 Days. Until March 2029, it will be reduced to 47 Days. Use Zero-Touch Certificate Management with Auto-Renewal, powered by NetScaler Console or NetScaler Console Service. www.julianjakob.com/netscaler-ze...

In the past, filtering published Apps visibility on Citrix #DaaS with Entra ID groups was only possible when linked to application groups. Now, you can add the filter on the published app, directly. But watch out regarding a minimum VDA version. www.julianjakob.com/citrix-daas-...

1/2 Watch out when using NetScaler integrated WAF for AAA and NSGW: There's an issue (NSCXLCM-7372 - confirmed for 14.1 Build 38.53, but I am able to reproduce it also with 34.42 and 29.72) where WAF configured for "AUTH and VPN" is blocking all NSGW Traffic after a HA-Failover took place.
