Errors are returned as
The value of the symbol
GSASL_OK is guaranteed to always be
0, and all other error codes are guaranteed to be non-
so you may use that information to build boolean expressions involving
return codes. Otherwise, an application should not depend on the
particular value for error codes, and are encouraged to use the
constants even for
GSASL_OK to improve readability. Possible

GSSAPI library could not deallocate memory in gss_release_buffer() in SASL library. This is a serious internal error.
GSSAPI library could not understand a peer name in gss_import_name() in SASL library. This is most likely due to incorrect service and/or hostnames.
GSSAPI error in client while negotiating security context in gss_init_sec_context() in SASL library. This is most likely due insufficient credentials or malicious interactions.
GSSAPI error in server while negotiating security context in gss_accept_sec_context() in SASL library. This is most likely due insufficient credentials or malicious interactions.
GSSAPI error while decrypting or decoding data in gss_unwrap() in SASL library. This is most likely due to data corruption.
GSSAPI error while encrypting or encoding data in gss_wrap() in SASL library.
GSSAPI error acquiring credentials in gss_acquire_cred() in SASL library. This is most likely due to not having the proper Kerberos key available in /etc/krb5.keytab on the server.
GSSAPI error creating a display name denoting the client in gss_display_name() in SASL library. This is probably because the client supplied bad data.
Other entity requested integrity or confidentiality protection in GSSAPI mechanism but this is currently not implemented.
