Ok. Setting ‘mac-address source type’ to ‘user-name’ fixed the issue. One last related question. Will changing this option in IDE have any impact on 802.1x authentications or is this setting only used for MacAuth?

No should not impact. Because you likely have various auth protocols enabled (incl. TLS and others) on the Authentication Policy, and the switch/AP will first attempt to auth via more secure protocols and IDE will respond accordingly.
