SAP IDM : Using regex for password

Question

Hi experts,
I need your help about regex.
We are trying to use this to be sure that password set in Web inteface by users are correct according to the company policies :
- The first character cannot be a number
- The three first characters cannot be the same
We finally found the following expression to test what we want (reponse is "true" when one of the policies is ok) :
(.)(1)|(d)
But IDM never accept any password with that expression.
So my questions are :
1) Does IDM need a special regex language or is it the same than PERL language for example?
2) Does anybody know how to use regex in our policies case?
Thanks a lot for your response.
Regards.
Jérémy.

Answer 1

Thanks a lot for your answers.
Actually, i am already doing my test on another attribut which is not encrypted. but yeah its a good point to know about the encryption.
I also tried to use evaluators on internet and my expression looks good if i want to catch cases that i dont want in my password...
as a reminder : (.)(\1)|(\d)
So if i write :
"1password"   >> result : true
"password"     >> result : false
"pppassword" >> result : true
"password01" >> result : false
"passwooord" >> result : false
but finally if i put that expression in the field "regex" of my attribut, IDM never let me save my new password because it's not a "correct value".
So im disapointed because i don't how to solve it in IDM but i feel like i found the good expression...
Any another idea?
