detect connection table full properly.

race condition on file descriptor sets.

Toy with dllimport/dllexport stuff (think I'll leave the real dll work to

Added ldap_strdup() wrapper of ber_strdup().

Make _MOD_SOFTADD 0x1000 to minimize chance of conflict with legit changes

Lose previously commented out old code.
Robustness fixes.
Fixed error reporting of non-existing attribute superior.

Added validation to exposed opaque data structures (BerElement, Sockbuf,
and LDAP).  Added macros BER_VALID, SOCKBUF_VALID, LDAP_VALID.
Added ber_pvt_ber_bytes() and ber_pvt_ber_remaining() macros to hide

Provide (and use) #define shortcuts
Really kill global_oc & global_at
Publish schema through LDAP (really, it's there at last :-)

First step in new schema support.

to avoid accessing c_conn_state after close.

locking requires and possibly restructure locking.

Fix compilation errors, mod declared as LDAPMod, but used inconsistently
