You can see that these two trace sequences are for the same authentication request because the artifact (AAMoz+rm2jQjDSHjea8U9zm3Td/U2ax0YZCo/qBNool8WkZiTCt7N7Jx) that is exchanged is the same. You can use the AMAUTHID in each file to search for other requests that this user has made.
To associate a distinguished name with the AMAUTHID, use the catalina.out file of Identity Server. Event AM#500105014 contains the DN of the user.
