Unable to use filters like 'member=uid=jprjr,ou=people...'

[jprjr]

I'm trying to do a search for groups that a user is a member of, as far as I can tell this filter is valid, assuming there's a group with a member named 'uid=jprjr' like:

(member=uid=john,ou=people,dc=example,dc=com)

But when I try to search I get a syntax error when compiling the filter.

In the anniversary of your comment. We have found that escaping the = character with \\3D solves the issue and the filter can be created.
