Later, it was found the error was due to lacking of two libraries:
==============================================
mbc80:/usr/lib <249> ldd libsasl2.so
        linux-gate.so.1 =>  (0xffffe000)
        libresolv.so.2 => /lib/libresolv.so.2 (0xb7ef0000)
        libssl.so.0.9.7 => /lib/libssl.so.0.9.7 (0xb7ebe000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7eba000)
        libmysqlclient.so.15 => not found
        libz.so.1 => /usr/lib/libz.so.1 (0xb7ea8000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7e7a000)
        libnsl.so.1 => /lib/libnsl.so.1 (0xb7e66000)
        libm.so.6 => /lib/libm.so.6 (0xb7e42000)
        libpq.so.4 => /usr/lib/libpq.so.4 (0xb7e23000)
        libldap-2.3.so.0 => not found
        libc.so.6 => /lib/libc.so.6 (0xb7d12000)
        libcrypto.so.0.9.7 => /lib/libcrypto.so.0.9.7 (0xb7c0a000)
        /lib/ld-linux.so.2 (0x80000000)
        libkrb5.so.3 => /lib/libkrb5.so.3 (0xb7b95000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7b82000)
        libk5crypto.so.3 => /lib/libk5crypto.so.3 (0xb7b5d000)
        libcom_err.so.3 => /lib/libcom_err.so.3 (0xb7b59000)
        libkrb5support.so.0 => /usr/lib/libkrb5support.so.0 (0xb7b56000)
==============================================
When I put these two libraries (libldap-2.3.so and libmysqlclient.so) into the printer, the error of "86 Unknown authentication method" disappears. 

Thanks,
