The FreeRDP libraries, when you connect to a server, *even when you tell it to ignore the certificate*, store a copy of the certificate fingerprint in a "known hosts" file, very similar to SSH. If the FreeRDP libraries are unable to write this file, because the Linux user account lacks write access to its own home directory, the connection *will fail.* I've run into this when running guacd under the "daemon" user account on EL-based platforms, as the "daemon" account generally has a home directory of /sbin, and generally cannot write to that directory. Make sure the account running guacd has a valid home directory, and write access to that directory. There may be other issues that need to be addressed, but this is one of the ones to verify. -Nick >
