#9895 Memory leaks in IPA plugins

Reopen Issue

Issue

Multiple memory leaks have been identified across various IPA plugins. These leaks occur in different scenarios including normal operations, error handling paths, and server shutdown.

The affected plugins are:
- ipa-enrollment
- ipa-extdom-extop
- ipa-graceperiod
- ipa-lockout
- ipa-pwd-extop
- ipa-range-check
- ipa-sidgen
- topology

Steps to Reproduce

  1. Edit /usr/lib/systemd/system/dirsrv@.service.d/custom.conf and follow instructions to enable AddressSanitizer, reload systemd, etc.
  2. Run upstream tests, they should trigger operations such as LDAP binds, password changes, lockout and graceperiod changes, host enrollment, topology/replication changes, etc.

Actual behavior

Memory leaks reported by AddressSanitizer under /var/run/dirsrv/slapd-INSTANCE

Expected behavior

No memory leaks
