Description

Hello,

I'm getting this error in the gitea logs

2022/10/18 21:09:34 ...dap/source_search.go:520:SearchEntries() [E] [634ef9ee-22] LDAP Search failed unexpectedly! (LDAP Result Code 4 "Size Limit Exceeded": )
2022/10/18 21:09:34 .../ldap/source_sync.go:49:Sync() [E] [634ef9ee-22] SyncExternalUsers LDAP source failure [REDACTED], skipped

1000 is the default limit from what i've read online. My organization has more than 1000 users so this error can be correct. To solve it it is possible to set something on the server side to losen this limit

... however ...

there are also LDAP clients which support pagination. See: https://www.tirasa.net/en/blog/getting-around-active-directory-search

gitea should not just throw in an error but instead use pagination on the LDAP protocol when it is supported (from version 7.2 i read online)

Thanks for support

There is an option to enable paged searching when adding/editing the authentication source:

Thanks @KN4CK3R that's cool.

The option could have been mentioned in the error message, or detection of the problem after which paged search can be enabled automatically. But seems like too low priority to keep this issue open.
