BUG: LDAP password change

Hello,

there is a bug that prevents users from changing thier passwords if the userDN contains a comma (e.g. cn=test, test1…).
Logfiles show the request being made as “cn=test\2C test1…” but i don’t get any error messages it just says “Unable to change password”. Removing the comma from the AD object instantly resolves this issue.

Environment info:
LDAP: MS Active Directory 2008
