Normally, after OpenDJ installation, when we use any OpenDJ commands under $OpenDJ_Path/bin, we have to include parameters like hostname, baseDN etc. For example:
./ldapsearch --hostname localhost --port 1389 --baseDN="ou=people,dc=example,dc=com" --bindDN="cn=directory manager" --bindPassword=yourpassword uid=* dn dn: uid=user.0,ou=people,dc=example,dc=com dn: uid=user.1,ou=people,dc=example,dc=com dn: uid=user.2,ou=people,dc=example,dc=com dn: uid=user.3,ou=people,dc=example,dc=com
This could be annoying and unsafe, because the user and password are in plain txt and can be reviewed from history.
We can apply a tip to solve this problem:
./ldapsearch uid=* dn dn: uid=user.0,ou=people,dc=example,dc=com dn: uid=user.1,ou=people,dc=example,dc=com dn: uid=user.2,ou=people,dc=example,dc=com dn: uid=user.3,ou=people,dc=example,dc=com
The secret is adding a tools.properties under ~/.opendj:
cat ~/.opendj/tools.properties hostname=localhost port=4444 bindDN=cn=Directory Manager bindPassword=yourpassword baseDN=ou=people,dc=example,dc=com searchScope=sub ldapsearch.port=1389 ldapcompare.port=1389 ldapmodify.port=1389 ldapdelete.port=1389 trustall=true
The location ~/.opendj will work for every version OpenDJ I tested. For OpenDJ 2.x, we can also put the tools.properties under $OpenDJ_Path/config/tools.properties
