+Subject: [PATCH] Fix SASL get/set options on big endian platforms
+
+The options OPT_X_SASL_SSF_MIN, OPT_X_SASL_SSF_MAX, and OPT_X_SASL_SSF
+take *ber_len_t as input and output arguments. ber_len_t is defined as
+unsigned long:
+
+```
+    /* LBER lengths (32 bits or larger) */
+    #define LBER_LEN_T long
+
+    typedef unsigned LBER_LEN_T ber_len_t;
+```
+
+Wrong type handling is causing issues on big endian platforms.
