Make changes on "Makefile" to qmail work properly with ldap:


 LDAPFLAGS=-DQLDAP_CLUSTER -DEXTERNAL_TODO -DDASH_EXT -DDATA_COMPRESS-DQMQP_COMPRESS -DSMTPEXECCHECK -DALTQUEUE -DBIGBROTHER
 # ZLIB needed for -DDATA_COMPRESS and -DQMQP_COMPRESS
 ZLIB=-lz
 # to enable the auto-maildir-make feature
 MDIRMAKE=-DAUTOMAILDIRMAKE
 # to enable the auto-homedir-make feature
 HDIRMAKE=-DAUTOHOMEDIRMAKE
 # on most systems we need this to make auth_pop and auth_imap
 SHADOWLIBS=-lcrypt
 # to enable the possibility to log and debug imap and pop

After that, setup qmail

Update slapd.conf by placing this line 'by:

Eg:

 access to attrs=userPassword
               by dn="uid=dovecot,ou=mail,dc=example2,dc=com" read
