Sun Ray 3.1 on Linux depends on openldap libraries that are linked against the OLD SASL Libs. The ones that include CRAM-MD5 (or more specifically, hmac_md5). In order to do that, I downloaded the cyrus-sasl-1.5.28 src.
A standard compile fails with these error messages:
db_berkeley.c: In function `berkeleydb_open':
db_berkeley.c:94: warning: passing arg 2 of pointer to function from incompatible pointer type
db_berkeley.c:94: warning: passing arg 4 of pointer to function makes pointer from integer without a cast
db_berkeley.c:94: error: too few arguments to function

Howard Chu explains that Cyrus SASLv1 libraries were never up-reved to include Berkeley 4.1 support. So one has to manually patch it.
Very simple.
a) Open the file libs/db_berkeley.c and at line 94, change
ret = (*mbdb)->open(*mbdb, path, NULL, DB_HASH, flags, 0660);
ret = (*mbdb)->open(*mbdb, NULL, path, NULL, DB_HASH, flags, 0660);
b) Open the file utils/sasldblistusers.c and at line 184, change
ret = (*mbdb)->open(*mbdb, path, NULL, DB_HASH, DB_CREATE, 0664);
to
ret = (*mbdb)->open(*mbdb, NULL, path, NULL, DB_HASH, DB_CREATE, 0664);
and compile.
I also had to gut a lot of the code in sample/ as it would not compile either. Since I’m not using the sample, I just commented out the code which would not compile.
