11.1 Error values
Errors are returned as an int. Except for the OK case an
application should always use the constants instead of their numeric
value. Applications are encouraged to use the constants even for OK
as it improves readability. Possible values are:
GSASL_OK- This value indicates success. The value of this error is guaranteed
to always be
0 so you may use it in boolean constructs.
GSASL_NEEDS_MORE- SASL mechanism needs more data
GSASL_UNKNOWN_MECHANISM- Unknown SASL mechanism
GSASL_MECHANISM_CALLED_TOO_MANY_TIMES- SASL mechanism called too many times
GSASL_MALLOC_ERROR- Memory allocation error in SASL library
GSASL_BASE64_ERROR- Base 64 coding error in SASL library
GSASL_CRYPTO_ERROR- Low-level crypto error in SASL library
GSASL_GSSAPI_RELEASE_BUFFER_ERROR- GSSAPI library could not deallocate memory in gss_release_buffer() in SASL library. This is a serious internal error.
GSASL_GSSAPI_IMPORT_NAME_ERROR- GSSAPI library could not understand a peer name in gss_import_name() in SASL library. This may be due to incorrect user supplied data.
GSASL_GSSAPI_INIT_SEC_CONTEXT_ERROR- 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.
GSASL_GSSAPI_ACCEPT_SEC_CONTEXT_ERROR- GSSAPI error in server while negotiating security context in gss_init_sec_context() in SASL library. This is most likely due insufficient credentials or malicious interactions.
GSASL_GSSAPI_UNWRAP_ERROR- GSSAPI error while decrypting or decoding data in gss_unwrap() in SASL library. This is most likely due to data corruption.
GSASL_GSSAPI_WRAP_ERROR- GSSAPI error while encrypting or encoding data in gss_wrap() in SASL library.
GSASL_GSSAPI_ACQUIRE_CRED_ERROR- 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.
GSASL_GSSAPI_DISPLAY_NAME_ERROR- 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.
GSASL_GSSAPI_UNSUPPORTED_PROTECTION_ERROR- Other entity requested integrity or confidentiality protection in GSSAPI mechanism but this is currently not implemented.
GSASL_MECHANISM_PARSE_ERROR- SASL mechanism could not parse input
GSASL_AUTHENTICATION_ERROR- Error authenticating user
GSASL_INTEGRITY_ERROR- Integrity error in application payload
GSASL_NO_CLIENT_CODE- Client-side functionality not available in library (application error)
GSASL_NO_SERVER_CODE- Server-side functionality not available in library (application error)
GSASL_NO_CALLBACK- No callback specified by caller (application error).
GSASL_NO_ANONYMOUS_TOKEN- Authentication failed because the anonymous token was not provided.
GSASL_NO_AUTHID- Authentication failed because the authentication identity was not provided.
GSASL_NO_AUTHZID- Authentication failed because the authorization identity was not provided.
GSASL_NO_PASSWORD- Authentication failed because the password was not provided.
GSASL_NO_PASSCODE- Authentication failed because the passcode was not provided.
GSASL_NO_PIN- Authentication failed because the pin code was not provided.
GSASL_NO_SERVICE- Authentication failed because the service name was not provided.
GSASL_NO_HOSTNAME- Authentication failed because the host name was not provided.
GSASL_SASLPREP_ERROR- Could not prepare internationalized (non-ASCII) string.
GSASL_TOO_SMALL_BUFFER- SASL function needs larger buffer (internal error)
GSASL_FOPEN_ERROR- Could not open file in SASL library
GSASL_FCLOSE_ERROR- Could not close file in SASL library
GSASL_CANNOT_GET_CTX- Cannot get internal library handle (library error)
GSASL_NEED_CLIENT_ANONYMOUS_CALLBACK- SASL mechanism needs gsasl_client_callback_anonymous() callback (application error)
GSASL_NEED_CLIENT_PASSWORD_CALLBACK- SASL mechanism needs gsasl_client_callback_password() callback (application error)
GSASL_NEED_CLIENT_PASSCODE_CALLBACK- SASL mechanism needs gsasl_client_callback_passcode() callback (application error)
GSASL_NEED_CLIENT_PIN_CALLBACK- SASL mechanism needs gsasl_client_callback_pin() callback (application error)
GSASL_NEED_CLIENT_AUTHORIZATION_ID_CALLBACK- SASL mechanism needs gsasl_client_callback_authorization_id() callback (application error)
GSASL_NEED_CLIENT_AUTHENTICATION_ID_CALLBACK- SASL mechanism needs gsasl_client_callback_authentication_id() callback (application error)
GSASL_NEED_CLIENT_SERVICE_CALLBACK- SASL mechanism needs gsasl_client_callback_service() callback (application error)
GSASL_NEED_SERVER_VALIDATE_CALLBACK- SASL mechanism needs gsasl_server_callback_validate() callback (application error)
