Now related ITSes need be audited and possibly closed.
Enhancements:
- re-styled code for better readability
- upgraded backend API to reflect recent changes
- LDAP schema is checked when loading SQL/LDAP mapping
- AttributeDescription/ObjectClass pointers used for more efficient
mapping lookup
- bervals used where string length is required often
- atomized write operations by committing at the end of each operation
and defaulting connection closure to rollback
- added LDAP access control to write operations
- fully implemented modrdn (with rdn attrs change, deleteoldrdn,
access check, parent/children check and more)
- added parent access control, children control to delete operation
- added structuralObjectClass operational attribute check and
value return on search
- added hasSubordinate operational attribute on demand
- search limits are appropriately enforced
- function backsql_strcat() has been made more efficient
- concat function has been made configurable by means of a pattern
- added config switches:
- fail_if_no_mapping write operations fail if there is no mapping
- has_ldapinfo_dn_ru overrides autodetect
- concat_pattern a string containing two '?' is used
(note that "?||?" should be more portable
than builtin function "CONCAT(?,?)")
- strcast_func cast of string constants in "SELECT DISTINCT statements (needed by PostgreSQL)
- upper_needs_cast cast the argument of upper when required
(basically when building dn substring queries)
Todo:
- add security checks for SQL statements that can be injected (?)
- re-test with previously supported RDBMs
- replace dn_ru and so with normalized dn (no need for upper() and so
in dn match)
- implement a backsql_normalize() function to replace the upper()
conversion routines
- note that subtree deletion, subtree renaming and so could be easily
implemented (rollback and consistency checks are available :)
- implement "lastmod" and other operational stuff (ldap_entries table ?)

manpage patch for ITS#1787.
- Let write operations return unwilling-to-perform after
'gentle shutdown' has been initiated.
- Change -1 to 2 in slapd_gentle_shutdown and slapd_shutdown, since
sig_atomic_t can be unsigned (ITS#1736). The 'gentle SIGHUP' patch
is older than ITS#1736 but was applied later, so it reintroduced
the problem.

It has just occurred to me - duh - that the process ID of a back-shell
command is a perfectly good unique ID for it, and more useful than
any connection id/message id thingy. Doesn't need extra arguments
to the shell commands either, except a pid: line to abandon.
And msgid: can still be removed in a future version.
Here is a patch.

Here is a patch which does what I described. Of course, someone has
to decide if that is the right solution:-)
- Add an "opid:" line to the input to back-shell commands.
- Add an "abandonid: <opid> line to back-shell/abandon input.
- Replace message id with opid in back-tcl arguments.
- Add an abandonid = <opid> argument to back-tcl/abandon.
An opid (operation ID) is a "connection ID/message ID" string. I
would have liked to use another name to avoid confusion with struct
slap_op->o_opid, but I could not think of another apt word.
This also fixes ITS#1784 and ITS#1792. Since calling conventions
changed anyway, I fixed back-shell by adding abandonid: and making
opid: always be the ID of the current operation.
