Odd authentication issue w/ iControl and Perl

Using the same authentication scheme as the samples in the SDK, I am receiving some odd authentication log messages. This _does_ authenticate and proceed with the rest of the script.

However, if we enable TACACS+ authentication, then this log message invalidates the user we're trying to authenticate with for a period of time, rendering our tools useless.

It looks like, at some point, the username is being garbled, but I'm not sure where. Any pointers would be much appreciated.

We're using iControl SDK 10.2.0 and BIG-IP software version 10.2.2 build 763.3

Thanks in advance!
