Run ldd on Postfix smtpd and check each linked Library with ldd for diffrent
Versions of the same library. Maybe your Postfix is linked against sasl2 and
ldap and the ldap-Library itself is linked against sasl1.

For example:

# ldd `postconf -h daemon_directory`/smtpd
        linux-gate.so.1 => (0xffffe000)
        libpcre.so.0 => /usr/lib/libpcre.so.0 (0x4003d000)
        libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x4004a000)
        libldap-2.2.so.7 => /usr/lib/libldap-2.2.so.7 (0x40061000)
        liblber-2.2.so.7 => /usr/lib/liblber-2.2.so.7 (0x40093000)
        libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x400a0000)
        libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x400d0000)
        libmysqlclient.so.14 => /usr/lib/libmysqlclient.so.14 (0x401c4000)
        libz.so.1 => /lib/libz.so.1 (0x402ca000)
        libm.so.6 => /lib/tls/libm.so.6 (0x402db000)
        libdb-4.3.so => /usr/lib/tls/libdb-4.3.so (0x402fe000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x403e4000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x403f9000)
        libc.so.6 => /lib/tls/libc.so.6 (0x4040d000)
        libdl.so.2 => /lib/libdl.so.2 (0x40526000)
        libcrypt.so.1 => /lib/libcrypt.so.1 (0x4052a000)
        /lib/ld-linux.so.2 (0x40000000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x4055c000)

# ldd /usr/lib/libldap-2.2.so.7
        linux-gate.so.1 => (0xffffe000)
        liblber-2.2.so.7 => /usr/lib/liblber-2.2.so.7 (0x40057000)
        libresolv.so.2 => /lib/libresolv.so.2 (0x40064000)
        libsasl2.so.2 => /usr/lib/libsasl2.so.2 (0x40077000)
        libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x4008e000)
        libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x400be000)
        libc.so.6 => /lib/tls/libc.so.6 (0x401b1000)
        libdl.so.2 => /lib/libdl.so.2 (0x402cb000)
        /lib/ld-linux.so.2 (0x80000000)

and so on...

Check for diffrent sasl-Versions, db-versions, ldap-versions...
