Anything accessing the RSA server on port 1812 udp is only doing a single user radius authentication...there is no listing of users or 'syncing' anything else that occurs on port 1812 udp. Refer to the article mentioned by Erica, it has detailed troubleshooting steps if radius user authentication is not working. Your picture of log messages about 'syncing users'...that sort of functionality would be solely within the Bomgar device and it's own configuration... not the RSA server... as an RSA server cannot provide any sort of 'list of users' (unless you were using RSA admin api's and that would be on a TCP port).
I have worked on a case with another customer and Bomgar, and the type and setup of Bomgar they wanted required some sort of LDAP lookup from Bomgar through the device doing the 2-factor auth (the RSA server). Went back and forth with Bomgar support and the customer, and indicated the RSA server only uses LDAP to confirm the userid for an incoming authentication, we will not do any sort of lookups to LDAP and provide outgoing data about LDAP. So be sure that you know the RSA server will only confirm if a user and passcode is valid.... an incoming userid is valid and not locked out, and that whatever was in the password field is a passcode (pin+token) and we send back access-accept or access-reject (and we could append radius return attributes for that userid if needed). We are not able to function as any LDAP or user sync or user lookup mechanism for Bomgar.
On Bomgar site, there is this note mentioned about doing Securid radius auths.

RADIUS Server for Authentication
To define group policies based upon groups within a remote server, you must configure both the LDAP group provider and the RADIUS user provider. You then must enable group lookup from the user provider's configuration page. One group security provider can be used to authorize users from multiple servers, including LDAP, RADIUS, and Kerberos.
LDAP Group Lookup
If you want users on this security provider to be associated with their groups on a separate LDAP server, choose one or more LDAP group servers to use for group lookup. Default Group Policy Each user who authenticates against an external server must be a member of at least one group policy in order to authenticat
This would mean you configure something entirely separate from the RSA server as your LDAP group provider, and then configure RSA server as the security provider. RSA server cannot do both roles.
