IBM Tivoli Directory Integrator - java.lang.IllegalArgumentException: Bad arguments

This one baffled me for a good 10-15 minutes on Friday.

When I ran any TDI script ( this is TDI 7.0.0.5 as used with Connections 3.0.1 ), including populate_from_dn_file.sh

I was getting really really cross as I couldn't see what had led to this problem. However, having just updated the SSL certificates between TDI and LDAP ( Active Directory ), I wasted a bit of time checking that the certificates were correct.

Then I remembered that I'd also updated the password in profiles_tdi.properties for the target database ( DB2 UDB ) ….

Even with that clue, it still took me two or three attempts to realise that, when I'd pasted the new password into profiles_tdi.properties, I'd inadvertently included a …. CR/LF character.

I was fooled because the encoded password wraps around onto a second line so I saw: -

{protect}-dbrepos_password={encr}f9dfa8r348rufdu9r8849089df8f89dfhdjhrkhwerjh32984r9fud9f9dsu90r[23ij4repdfua9sudf90[dsr0u2390ruefjaf
9832rufdifp8dsgy7sysuhuhrh3ur3y48dfsf8sdafkjhlkhrew

and read it as: -

{protect}-dbrepos_password={encr}f9dfa8r348rufdu9r8849089df8f89dfhdjhrkhwerjh32984r9fud9f9dsu90r[23ij4repdfua9sudf90[dsr0u2390ruefjaf9832rufdifp8dsgy7sysuhuhrh3ur3y48dfsf8sdafkjhlkhrew

whereas it was actually stored in the file as: -

{protect}-dbrepos_password={encr}f9dfa8r348rufdu9r8849089df8f89dfhdjhrkhwerjh32984r9fud9f9dsu90r[23ij4repdfua9sudf90[dsr0u2390ruefjaf [CR/LF]
9832rufdifp8dsgy7sysuhuhrh3ur3y48dfsf8sdafkjhlkhrew

meaning that TDI didn't know what to with this line: -

9832rufdifp8dsgy7sysuhuhrh3ur3y48dfsf8sdafkjhlkhrew

in its properties file, hence the nasty ( but actually quite revealing ) java.lang.IllegalArgumentException.

Bottom line, check your property files, and avoid copy/paste.

Newbie error :-)
